You have standard hose bibs on the side of the house and want one cover for each, from the maker’s own first choice for freeze protection.

The faucet stands in the yard on a pipe, or sits where a mower or a dog will knock it. Get a sock or the hard FC2.
Most outdoor faucets are a plain hose bib on the side of the house, and that’s the faucet Frost King’s FC1 is made for. Frost King lists it as a foam, oval cover that fits an outside faucet. Its own answer on which cover to use is plain: foam is the best bet for keeping a faucet from freezing.
Here’s what a cover does. It adds no heat. It closes in the faucet so the heat that reaches it through the pipe from the house stays around the valve longer, and wind can’t carry that heat away. Frost King says the cover protects against freezing wind and chill.
That’s why the cover must sit tight to the siding. A gap at the bottom lets cold air wash through and the foam does much less. Take the hose off first. The Red Cross says to remove, drain and store outdoor hoses, and a hose left on the spout holds the cover away from the wall.
The FC1 has a second job. Frost King says these covers keep outside air from leaking into the home all year. If the hole where the pipe goes through your siding was never sealed, leaving the cover on can block that draft until you caulk it.
This listing is a 4-pack, part FC14A. Frost King’s site lists the single cover’s UPC as 077578018157. Count your faucets before you order. You need one cover for each, and a spare helps if one cracks or goes missing in a storm.
Know its limits. A cover helps most on a standard hose bib, where the valve and the water in it sit outside the wall. In a long, hard freeze, it backs up the real fix: close the inside shut-off valve and drain the faucet, as the Red Cross says.
For a stand faucet out in the yard, pick a cover listed for stand faucets, like the FC2 or a sock. Amazon.com sold the 4-pack new and in stock when we checked on Oct 21, 2026, and the listing says it’s made in the USA.

The faucet sits by a driveway, a mowing path or a dog run, where a soft dome would get crushed or chewed.
Skip it if
The faucet is tucked out of harm’s way. The foam FC1 is Frost King’s first choice for freeze protection.
Foam is soft. If a faucet sits where a mower, a bike or a dog can hit it, a foam dome gets crushed or chewed. Frost King’s FAQ covers this case: if you need something more durable, to protect against knocks or animals in the area, go with the hard plastic cover. That’s the FC2.
It’s built in two layers. Frost King describes a hard plastic outer shell plus a poly foam inner cover that gives long-lasting insulation. The shell takes the hits, and the foam liner does the insulating against the faucet.
The shape is rectangular, not oval, per Frost King. The Amazon listing says it insulates and protects regular and stand outdoor faucets, so try it on a short faucet near the ground too. Check the fit before the first freeze. A cover that rocks on its faucet lets cold air in.
Put it on the same way as the foam cover. Take the hose off. Close the inside shut-off valve if your faucet has one, open the outside faucet to drain it, and leave it open. Then set the cover over the faucet so its open side sits flat against the wall.
Frost King still puts foam first for freeze protection alone. So use the FC2 where damage is the bigger risk and the FC1 everywhere else. Mixing the two around one house is fine. The FC2 comes as a single, so buy one for each exposed spot.
On a frost-free faucet, you may not need either cover. Woodford says its Model 17 frost-free faucet won’t burst from freezing when the valve is shut off and the hose is removed. A hard cover there is armor against knocks, not a freeze fix.
The dark red shell is easy to see from across the yard, which helps when you check that every cover is still on after a windy night. Frost King lists it as part FC2, UPC 077578018140. Amazon.com sold it new and in stock when we checked on Oct 21, 2026.

Your faucet stands on a pipe in the yard, or has a shape a rigid dome won’t close around.
Skip it if
It’s a plain hose bib in a spot that gets knocked. The hard FC2 holds up better.
Not every outdoor faucet is a hose bib on a flat wall. Yard faucets on a pipe, faucets with big handles and odd shapes don’t close up inside a rigid dome. PF WaterWorks’ NoFREEZE cover is a soft insulated sock. It slides over the faucet and cinches shut at the bottom with a lock tie string.
Inside is 3M Thinsulate insulation, and the outside is a waterproof fabric, per PF WaterWorks. A soft cover follows an odd shape more closely than a dome can. The tie string pulls the opening snug around the pipe, so wind can’t blow straight up inside.
Size is the whole decision. PF WaterWorks says the Small fits most wall faucets and the Medium fits most wall and ground faucets. Amazon’s listing titles give the Small as 6 by 7 inches, sold as a 2-pack (PF0690-2), and the Medium as 8 by 20 inches (PF0691).
The Medium’s length is what makes it the ground faucet pick. At 20 inches, it can drop over a faucet on a short stand pipe and cover the exposed pipe below the valve, where a short cover stops at the faucet body. Measure from the top of the handle to the ground before you order.
For a wall hose bib, the Small does the same job as a foam dome. It’s light, too: the listing gives 0.13 pounds. Fabric folds flat, so the 2-pack takes little room in a drawer over the summer.
Fabric won’t stand up to a mower or a dog the way the FC2’s hard shell does. If the faucet sits in a busy spot, the hard cover is the better choice there. Pull the tie snug each time you put the sock on, because a loose bottom lets the wind in.
Amazon lists the brand as PermaFLOW, with PF WaterWorks as the maker. Amazon.com sold both sizes new when we checked on Oct 21, 2026. The Medium showed few left in stock, so check before you count on it.

Your lawn sprinkler system has a backflow assembly above ground near the house, and you want insulation over the valves after it’s drained.
Skip it if
You only need to cover hose bibs. The Small or Medium sock, or a foam dome, fits those.
Many lawn sprinkler systems have a backflow assembly above ground: a cluster of valves on two pipes sticking up near the house. The Red Cross lists sprinkler lines among the pipes that freeze most often. PF WaterWorks says its Large, Tall Large and Extra Large NoFREEZE covers fit most sprinkler vacuum breakers.
Draining comes first. The Red Cross says to drain water from sprinkler supply lines following the maker’s or installer’s directions, and not to put antifreeze in them unless directed. A cover goes on after that, to protect the valves and any water left inside them.
Size matters more here than on a hose bib. Amazon’s listing titles give the Large (PF0692) as 18 by 18 inches and the X Large (PF0693) as 24 by 24 inches. PF’s listing says to measure the distance between the pipes to be covered and order the correct size.
Measure the assembly at its widest, across both pipes and the valve body, and its height from the ground to the top. Pick the size that’s bigger in both directions, with room for the tie string to close around the pipes at the bottom. PF also lists a Tall Large for assemblies that are taller than they are wide.
Like the smaller covers, these are 3M Thinsulate inside waterproof fabric, per PF WaterWorks, and they close with a lock tie string. They slide on and off, which matters on a system you may need to open up or have tested in spring.
A cover doesn’t replace the shut-off. If your backflow assembly has its own shut-off valves, the installer’s directions are the ones to follow for draining it. Our backflow preventer guide explains the main types.
One thing to watch when you order: both listings use the same product photo, so check the size in the title before you add one to your cart. Amazon.com sold both sizes new and in stock when we checked on Oct 21, 2026.

Not sure which you have? Go inside and look behind the outdoor faucet. If you find a separate valve on the pipe near the wall, it’s likely a standard hose bib with its own shut-off. If the faucet’s body runs deep into the wall and there’s no valve near it, it’s likely frost-free.
Woodford’s frost-free wall faucets are made for walls from 4 to 24 inches thick and go in through a 1-1/8 inch hole, per its catalog and install sheet. That long body is the tell. Our sillcock vs hose bib guide shows more ways to tell them apart.
Do outdoor faucet covers work?
Yes, on the right faucet and with the right steps. A cover slows the loss of heat at the faucet. It doesn’t add heat, and it can’t save a faucet that’s full of water in a long, hard freeze.

It keeps wind off the faucet
Frost King says its covers protect against freezing wind and chill. Wind strips heat from bare metal fast.
It holds in heat from the house
A little heat travels out along the pipe from inside. A cover tight to the wall keeps it around the valve.
It adds no heat of its own
In a long cold snap, an insulated faucet still cools down. Shutting off and draining is what keeps it from bursting.
It can’t help with the hose on
Woodford warns that a frost-free faucet can freeze and burst if the hose stays on. A hose also holds the cover off the wall.
The drawing shows why the two kinds of faucet are so different. On a standard hose bib, the valve and the water behind it sit at the outside face of the wall. That’s where the freeze happens, and it’s where a cover does its job. The inside shut-off lets you empty that short stretch of pipe.
On a frost-free sillcock, the valve seat sits at the end of a long tube inside the heated space. When you close the handle, the water stops in the warm room and the tube drains out through the spout. That’s why Woodford says its supply connection must be in a heated space.
Do frost-free faucets need a cover?
Usually not, if the faucet was put in right and the hose comes off. Woodford’s instructions spell out the three things a frost-free faucet needs to drain and stay safe.
A downward pitch
Woodford says the tube must have a slight downward pitch for proper drainage, toward the spout.
A supply in the heated space
The water supply connection must be inside a heated space, per Woodford’s install sheet.
The hose removed in freezing weather
Woodford’s catalog warns that the faucet may freeze and burst if the hose isn’t removed.
A faucet that doesn’t drain
If water keeps dribbling out long after you close it, or the pitch looks flat, cover it and have it checked.
Woodford says its Model 17 won’t rupture from freezing when the valve is shut off and the hose is removed. The Model 17 also has backflow protection built in, rated to 125 psi, so it doesn’t need an add-on vacuum breaker. The Model 14 has no anti-siphon protection.
A cover on a frost-free faucet does no harm, and it can block a draft around the hole in the wall. It won’t fix a faucet put in level or left with the hose on. If yours is old or leaking, our frost-free spigot guide covers replacements, and our Woodford repair kit guide lists the parts.
How to cover an outdoor faucet the right way
The cover is the last step, not the first. These steps follow the Red Cross’s advice on outdoor hose bibs, with Woodford’s rules for frost-free faucets.
1
Do it before the first hard freeze
The Red Cross says to protect pipes before the onset of cold weather. A faucet that froze once may already be cracked.
2
Take the hose off
Remove, drain and store outdoor hoses, per the Red Cross. Woodford warns a frost-free faucet can burst with a hose left on.
3
Close the inside shut-off
On a standard hose bib, close the valve inside that feeds the outdoor faucet. A frost-free faucet usually has no separate valve.
4
Open the outside faucet and leave it open
The Red Cross says to open the outside hose bib to drain it, and keep it open so any water left can expand without breaking the pipe.
5
Fit the cover tight to the wall
Seat the open side flat on the siding. On a sock, pull the tie string snug around the pipe so wind can’t get in.
6
Check after storms
Wind and animals can knock a cover loose. A quick look after a storm is enough.
On a frost-free sillcock, close the faucet, take the hose off and watch the spout. It should drain for a moment and then stop. Then the cover is optional. For the full seasonal job, including the inside valves and the hose, see our guide to winterizing outdoor faucets.
How to choose the right size cover
Rigid covers come in one size. Soft covers come in several, and the wrong one either won’t close or flaps in the wind. Measure the faucet with the hose off before you order.
The Medium is long and narrow for faucets on a pipe; the Large and X Large are square for sprinkler valves.
Take three measurements. How far the faucet sticks out from the wall, from the siding to the front of the spout. How tall it is, from the top of the handle to the bottom of the spout. And how wide it is across the handle. Add a little room so the cover closes without pressing on the handle.
A vacuum breaker cap on the spout adds length, so measure with it on. Duck’s soft cover is a cheaper soft option for a plain wall faucet. Its listing says it secures around the spout and slides on and off.
Cover, drip, heat cable or Freeze Miser?
A cover is one tool among a few. Here’s what each one is for, so you can pick the one that matches how you use the faucet.
The Freeze Miser isn’t a cover. It threads onto a faucet you use all winter and opens only when the water reaching it drops below 37°F, so moving water pulls warmer water up from the pipe underground. Freeze Miser says it needs the faucet fully open and at least 10 PSI, and one unit protects up to 150 ft of hose kept off the ground.
Expect it to run for 2 to 5 minutes when you first put it on. The listing says it’s not for drinking water. If it fails, Freeze Miser says it fails open, and it carries a 2-year limited warranty. See the Freeze Miser 2-pack on Amazon.
You may need two of these. Shut off and drain the faucets you don’t use in winter, and put a cover on each. If one faucet must stay on, that’s the one for a Freeze Miser. Exposed pipe in a crawl space or garage is a heat cable job; our heat tape guide compares five.
Will a towel or a bag keep a faucet from freezing?
As a one-night stopgap, a little. As a winter plan, no. It’s the same idea as a cover, done worse.
Better than nothing for one night
The Red Cross says even ¼ inch of newspaper can give some protection where freezes are rare and short.
Wet cloth stops insulating
Rain or snow soaks a towel, and a soaked towel holds cold water against the faucet.
Hard to seal against the wall
Wind gets in around a towel held on with tape or string. A cover closes against the siding.
Shut off and drain anyway
With the faucet empty, a towel or a cover matters much less.
If a freeze is coming tonight and you have no cover, wrap the faucet in a dry towel, pull a plastic bag over it to keep it dry, and tie it off below the faucet. Then close the inside shut-off and open the faucet. Order a real cover for the rest of the winter.
Mistakes that crack faucets anyway
A cover can’t make up for these slips. Each one can let a covered faucet freeze anyway.
Leaving the hose on
Woodford warns a frost-free faucet may freeze and burst with a hose attached. Take it off every time.
Closing the outside faucet after draining
The Red Cross says keep the outside valve open, so any water left inside can expand without breaking the pipe.
A gap under the cover
Cold air flows in at the bottom. Seat the cover flat, and snug the tie on a sock.
The Red Cross says don’t, unless the maker or installer directs it. It harms people, pets and plants.
Turning down a Freeze Miser
The maker warns that cutting the pressure to slow the drip can freeze the line.
Don’t forget the pipes you can’t see. The Red Cross lists pipes in crawl spaces, attics, garages and kitchen cabinets, and pipes on outside walls with little insulation, among those that freeze most. A covered faucet can’t help a frozen pipe a few feet inside the wall. Our pipe insulation guide covers those.
If the faucet froze anyway
The Red Cross says to suspect a frozen pipe when you turn on a faucet and only a trickle comes out. These steps follow its advice.
1
Keep the faucet open
As the ice melts, running water helps melt more of it.
2
Warm the pipe, not the room
The Red Cross lists a heating pad, a hair dryer, a space heater kept away from anything that burns, or towels soaked in hot water.
3
Never use an open flame
No blowtorch, kerosene or propane heater, or charcoal stove, per the Red Cross.
4
Heat until full pressure returns
Then check every other faucet in the house for frozen pipes too.
5
Call a licensed plumber if needed
If you can’t find the frozen spot, can’t reach it or can’t thaw it, the Red Cross says to call a licensed plumber.
Watch for leaks once it thaws. A frost-free faucet can crack inside the wall, so the first time you open it, look inside for water around the pipe. Our guide to thawing frozen pipes walks through the rest.
Questions people ask
What is the best cover for outdoor water faucets?
For a standard wall hose bib, a foam cover like Frost King’s FC1, which Frost King calls the best bet against freezing. Where a faucet gets knocked or chewed, use the hard FC2. For yard faucets and sprinkler valves, use a soft insulated sock in the right size.
Do outside faucet covers really work?
Yes, as part of the job. A cover keeps wind off the faucet and holds in heat that reaches it from the house. It adds no heat, so in a hard freeze you still close the inside shut-off and drain the faucet.
What is the best way to cover outside faucets?
Take the hose off, close the inside shut-off valve, open the outside faucet to drain and leave it open. Then fit the cover tight against the wall, with no gap at the bottom.
Will wrapping a towel around an outdoor faucet keep it from freezing?
For one night, a dry towel under a plastic bag helps a little. The Red Cross says even ¼ inch of newspaper gives some protection where freezes are short. A wet towel holds cold water against the faucet, so use a real cover for the winter.
How do I choose the right size outdoor faucet cover?
Measure with the hose off: depth from the wall to the front of the spout, height from the top of the handle to the bottom of the spout, and width across the handle. Rigid covers come in one size. For soft covers, PF WaterWorks says the Small fits most wall faucets and the Medium fits wall and ground faucets.
Are outdoor faucet covers necessary?
On a standard hose bib in a cold climate, a cover is cheap insurance. On a frost-free faucet with the hose off, Woodford says the faucet won’t burst from freezing, so a cover is optional.
Do frost-free faucets need a cover?
Usually not. Woodford’s frost-free Model 17 won’t rupture from freezing when it’s shut off with the hose removed, as long as it pitches down and its supply is in a heated space. A cover still blocks drafts.
Should I leave the outside faucet open or closed in winter?
On a standard hose bib, close the inside shut-off and leave the outside faucet open, as the Red Cross says, so leftover water can expand. On a frost-free faucet, close it and take the hose off.
Can I leave the hose connected if I use a cover?
No. A hose holds water in the faucet and keeps the cover off the wall. Woodford warns a frost-free faucet can burst with a hose left on. The Freeze Miser is the one exception, and its maker covers up to 150 feet of hose.
Is a hard faucet cover better than a foam one?
Not for insulation. Frost King says foam is the best bet for freeze protection, and its hard FC2 is for spots where knocks or animals would damage foam.
When should I put faucet covers on?
Before the first hard freeze. The Red Cross says to protect pipes before cold weather starts. Leave them on until the last frost, then store them dry.
How we picked these covers
Why trust us
Isaac Daniels, a licensed journeyman plumber in Georgia (license #JP507711), owns PlumbingPicks and is responsible for this page. The fit and freeze facts come from Frost King, PF WaterWorks, Freeze Miser and Woodford, plus the American Red Cross, read the same night we checked the listings.
How we pick
Covers matched to the kind of faucet they fit, using each maker’s own fit statements and the sizes in the listing titles.
Frost-free rules from Woodford’s Model 14 and 17 install sheet and Model 17 catalog sheet. Shut-off, drain and thaw steps from the American Red Cross.
The spec score checks whether the cover’s size is published, knock protection, the outside material and how many sizes the line comes in. Insulation isn’t scored, since the maker pages we read give no insulation number.
Every listing checked as a genuine branded product, new and in stock, through Amazon’s Creators API on Oct 20 and again Oct 21, 2026.
CPSC recalls searched for each brand and for faucet covers.
The spec score, check by check
Each cover gets the same four checks, read from Frost King’s and PF WaterWorks’ pages and the listing titles, averaged to one decimal. Every pick has to reach 7.0.
Insulation isn’t in the score, because the maker pages we read name the insulation but give no number to compare it by. The FC1 scores lowest, but Frost King itself calls foam the best bet against freezing, and it’s still our pick for a plain wall hose bib.
