Camlock fittings join hoses with two cam arms, no tools. The letter says the ends: Type C is a coupler to a hose shank. For a 2 in. Type C, get Dixon’s RC200CEZ: 316 stainless, 250 psi, locking arms.

How the three compare on our spec score
Five checks from each maker’s product page and documents, equal weight. The rules and every input are in the method section near the end.
PlumbingPicks spec score out of 10, from Dixon’s and Banjo’s product pages and Banjo’s drawing, read Oct 23, 2026. It is not a customer rating or a lab test of our own.
The checks are what you need to know before liquid goes through a camlock: its pressure rating, its gasket, the standard it’s built to mate with, what fluids the maker says it’s for, and whether the arms lock.
Dixon answers all five for its stainless Boss-Lock coupler. The aluminum Dixon has no lock. Banjo gives a pressure rating and gasket but no named standard or fluid list on its page.
Each coupler, in detail
What each maker publishes, what it means for your hose and fluid, and where each one lost points.
Best for locking arms
Dixon RC200CEZ
EZ Boss-Lock Type C coupler x hose shank with collar, 2 in., 316 stainless steel
The hose moves around, drags, or carries something you can’t have it drop, and you want arms that lock.
Skip it if
You want the lightest fitting for a hand-carried hose. The Banjo is a fraction of the weight.
The RC200CEZ is the camlock I’d put on a working hose, and I’ve used it. It’s Dixon’s EZ Boss-Lock Type C coupler: a female cam end on one side, a collared hose shank on the other, in 316 stainless steel.
The lock is why it’s my top pick. Dixon says the cast-in lugs let safety clips pass through slots in the special cam arms for a positive lock, and the pull-ring clips mean no inserting pins or dangling lanyards; you twist and it’s locked.
That matters because an unlocked cam arm can be knocked open by a hose dragged across the ground. On a pressurized line, that’s the failure you don’t want.
Dixon rates it at 250 psi maximum operating pressure, with a footnote worth reading: ratings assume mating Dixon fittings at about 70°F with a standard seal. At higher temperatures, Dixon says to consult them.
The gasket is nitrile rubber, and Dixon says other gasket types are available on request. The listing describes the Boss-Lock design as rotating to keep the locking device free of debris.
It’s produced to interchange with all products made to Commercial Item Description A-A-59326D. That’s the standard that lets a Dixon coupler mate with another maker’s adapter of the same size.
Dixon’s page lists it for liquids and says to consult Dixon for specific recommendations, and it’s blunt on one point: never use cam and groove couplings for compressed air or steam.
Dixon lists it as 2 in. (50 mm) and offers a CAD drawing on the product page. The EZ Boss-Lock family also includes a Type D coupler with a female NPT end, so the same locking arms can go on a threaded tank or pump connection.
My call: at 2.6 lb, it’s heavy for a hand-carried hose but right for a pump discharge or a tank connection that stays put.
Best for fuel and water hose
Dixon G200-C-AL
Global Type C coupler x hose shank, 2 in., cast aluminum with brass handles
You’re moving water or fuel through a 2 in. hose and want a light, standard aluminum coupler.
Skip it if
The hose gets dragged or bumped and an arm could flip open. Take the Boss-Lock.
The G200-C-AL is Dixon’s Global aluminum Type C, and I’ve used it. It’s the classic camlock: a cast aluminum body with brass cam handles, a female coupler on one end and a hose shank on the other.
Dixon lists the body as A383 cast aluminum and the weight at 1.045 lb, under half the stainless Boss-Lock. The maximum operating pressure is the same 250 psi, under the same conditions: mating Dixon fittings, about 70°F, standard seal.
The seal is nitrile rubber. The Amazon listing says that seal is rated for petroleum service, ethanol to E100 and biodiesel to B20. That’s why it’s my pick for fuel and water transfer hose.
Dixon says it’s designed to interchange with all products made to A-A-59326D, so it mates with any compliant 2 in. adapter.
Coupling is simple, per Dixon: slide the adapter in and press the cam levers down by hand. To uncouple, lift the cam arms and pull the adapter out.
Where it lost points: the arms don’t lock, so it scored 7 on that check. Dixon sells locking versions; on this one, you’re relying on the cam arms staying down.
Dixon’s safety notes apply here too: liquids only, consult Dixon for specific fluids, and never for compressed air or steam.
The Global line has matching parts: Dixon sells Global Type E adapters with hose shanks, jump-size adapters, and replacement cam handles for its aluminum and brass Global couplers. A Global Type E on the other end of the hose gives you a matched pair.
My call: the listing showed only 2 left on Oct 23, 2026. If it’s out, the card stays and the price hides until it’s back, and Dixon’s 200-C-AL is the same size in 356T6 aluminum.
Best for a light poly fitting
Banjo 200C
Polypropylene Type C female coupler x hose shank, 2 in.
You want the lightest 2 in. coupler, with an EPDM gasket, and you’ll confirm your fluid with Banjo.
Skip it if
You’re moving fuel. Banjo’s page doesn’t list it; the nitrile-sealed Dixon does.
Banjo’s 200C is the poly pick, and I’ve used it. Banjo says it makes the most complete line of polypropylene couplings available, in sizes from ½ in. to 3 in.
Banjo’s page gives a maximum operating pressure of 225 psi, EPDM gaskets, and stainless steel rings, arms and pins. It weighs 0.559 lb, about half the aluminum Dixon.
Banjo’s drawing (200C) breaks it into five parts: the decal, two cam arms, the 200G 2 in. gasket, two cam arm pins and the 200XC coupler body with a 2 in. hose barb.
The listing from a different seller says 100 psi at 0°F for ½ in. to 2 in. sizes; Banjo’s own page says 225 psi. Use Banjo’s figure, and treat cold service as a reason to ask Banjo.
Banjo says it’s interchangeable with all types of cam lever couplers, but its page doesn’t name a standard the way Dixon’s does, so it scored 7 on that check. It also has no fluid list on the page, which scored a 7.
Banjo’s warning is the one to tape to the pump: couplings should not be disconnected under pressure or with liquid in the line.
A reseller’s listing describes it for chemicals and other liquids, but Banjo’s own page doesn’t list fluids. Polypropylene isn’t right for every chemical, so check Banjo’s compatibility guidance for your fluid before you buy.
Banjo also makes the same coupler as a 90-degree elbow, the 200C90, with a 2 in. hose shank, for a hose that has to turn sharply at a tank or pump.
My call: for a portable water or spray hose that’s carried all day, the weight savings are real. For fuel, take the Dixon.

Covers an adapter when not in use
The quickest way to remember it: couplers have the arms, adapters have the groove. A hose usually has a Type C on one end and a Type E on the other, so two hoses can join end to end.
NPT threads are tapered pipe threads, and male versus female matters. Our MIP vs FIP guide explains how to tell them apart, and our thread sealant notes cover the threaded end.
How camlock sizes work
The size is the nominal hose or pipe size. A 2 in. coupler takes a 2 in. adapter, and a 2 in. hose shank goes into a 2 in. ID hose.
What you have
How to size it
Note
A hose
Its inside diameter (ID)
Dixon lists the G200 as 2 in. hose ID barbed
A threaded port
The nominal pipe size of the NPT thread
Not the outside diameter you measure
An existing camlock
The size cast or stamped on it
Couplers and adapters must be the same size
Two different sizes
A reducer fitting
Dixon sells reducing fittings, such as 5 in. × 4 in.
Banjo makes its poly couplers in ½, ¾, 1, 1¼, 1½, 2 and 3 in. Dixon’s range runs larger; it sells 4 in. tank car adapters and 5 in. × 4 in. reducers, for example.
My call: measure a hose by its inside diameter, not the outside. A 2 in. ID discharge hose takes a 2 in. Type C or E, whatever its wall thickness.
Material and gasket: what the makers say
The body and the gasket decide what a camlock can carry. Here’s what each maker publishes for these three.
Pick
Body
Gasket
What the maker says it’s for
Dixon RC200CEZ
316 stainless steel
Nitrile; others by request
Liquids; consult Dixon for specific recommendations
Maximum operating pressure from Dixon’s and Banjo’s product pages, on a 300 psi scale, read Oct 23, 2026. Dixon’s figures assume mating Dixon fittings at about 70°F with a standard seal.
Gasket material is the part people forget. As a general rule, nitrile is the common choice for fuels and oils, and EPDM for water and many chemicals but not petroleum. Neither maker publishes a full chemical chart on these product pages, so check the maker’s chart for your exact fluid and temperature.
My call: never guess chemical compatibility on a camlock carrying anything other than water. Call the maker with the fluid name and temperature, and get the answer in writing.
Safety rules the makers print
Camlocks are quick to connect and quick to come apart. These are the rules from the makers’ own pages.
Never for compressed air or steam
Dixon: “Under no circumstances should cam and groove couplings be used for compressed air or steam service.”
Never disconnect under pressure
Banjo: couplings should not be disconnected under pressure or with liquid in the line.
Pressure ratings have conditions
Dixon’s 250 psi assumes mating Dixon fittings at about 70°F with a standard seal. Consult the maker for other conditions.
Lock the arms on moving hose
Boss-Lock style arms with safety clips keep a dragged hose from knocking a cam arm open.
Match sizes and the standard
Dixon builds to interchange with A-A-59326D; mate same-size parts.
My call: shut the pump off and open a valve or drain to bleed the line before you lift the arms. Liquid in a hose under pressure will spray the moment the gasket unseats.
How to connect and disconnect a camlock
Dixon’s description, step by step, with the checks I’d add.
1
Check the gasket
Look inside the coupler. The gasket should be seated, clean and uncracked.
2
Slide the adapter in
Push the male adapter straight into the coupler until it bottoms.
3
Press the cam arms down
Dixon: with normal hand pressure, press both levers down. They should close evenly.
4
Lock the arms if you can
On Boss-Lock couplers, twist the pull-ring clips to lock.
5
To disconnect
Stop the pump, relieve pressure, then lift the cam arms and pull the adapter out, per Dixon.
A leak at a camlock is almost always the gasket: missing, twisted, or the wrong material for the fluid. Banjo lists its 2 in. gasket as part 200G; Dixon sells cam and groove gaskets by size.
The hose shank end needs its own clamp, sized for the hose. That clamp, not the camlock, is what keeps the hose on the fitting.
Keeping camlocks sealing
My call on the small habits that keep a camlock from leaking.
Habit
Why
Cap open ends
Dirt in a groove or coupler scores the gasket; Dixon sells dust caps (Type DC)
Carry spare gaskets
A torn gasket is the most common leak; Banjo lists its 2 in. gasket as part 200G
Rinse after chemicals
Residue left in the coupler can attack the gasket between uses
Check the arms and pins
A bent arm won’t pull the adapter tight against the gasket

Questions people ask
What are camlock fittings?
Cam and groove couplings: a female coupler with two cam arms clamps onto a male grooved adapter, sealed by a gasket, with no tools.
What is a Type C camlock?
A female cam coupler on one end and a hose shank on the other. It’s the usual fitting on the end of a pump or transfer hose.
What’s the difference between Type C and Type E?
Type C is a coupler (with arms) × hose shank; Type E is an adapter (grooved) × hose shank. A hose often has one of each.
Are camlock fittings interchangeable between brands?
Dixon builds its couplers to interchange with products made to A-A-59326D, and Banjo says its couplers interchange with all cam lever types. Match the size.
What pressure are camlock fittings rated for?
Dixon rates its 2 in. Type C couplers here at 250 psi, and Banjo its 2 in. poly coupler at 225 psi. Ratings depend on size, material, temperature and seal.
Can camlock fittings be used for air?
No. Dixon says cam and groove couplings should never be used for compressed air or steam.
Can you disconnect a camlock under pressure?
No. Banjo says never to disconnect under pressure or with liquid in the line.
What gasket comes in a camlock?
Both Dixon couplers here use nitrile; the Banjo uses EPDM. Dixon offers other gasket materials on request.
Which camlock is best for fuel?
The Dixon G200-C-AL; its listing says the nitrile seal is rated for petroleum, ethanol to E100 and biodiesel to B20.
What are locking camlock fittings?
Couplers whose arms lock closed, like Dixon’s Boss-Lock with pull-ring safety clips, so a cam arm can’t be knocked open.
How do I measure a camlock size?
Use the hose’s inside diameter or the nominal pipe size of the thread. Couplers and adapters must be the same size.
How we picked these
Why trust me
I’m Isaac Daniels, a licensed journeyman plumber in Georgia (license #JP507711), and I’ve used all three picks.
