Best Type A Adapter
Best Hose-Shank Coupler
Camlock fittings are useful when you want a large water hose to connect and disconnect without spinning threaded couplings every time. The two cam arms on the female side pull a male adapter into the gasket, creating a quick mechanical connection for a tank, transfer pump, discharge hose, or temporary irrigation line.
The hard part is that "2-inch camlock" does not describe the whole fitting. Type A, B, C, D, and F ends all use the same general cam-and-groove family but place male adapters, female couplers, NPT threads, and hose shanks in different combinations. Buying the wrong type can leave you with two male ends or two threaded ends that cannot connect to the equipment you already own.
All five products here are 2-inch Banjo-style fittings. Choose the type from the connection needed on each side, then check the actual tank valve or pump thread before ordering. Some IBC tote outlets look like 2-inch pipe fittings while using different threads, so never force an NPT part onto a tote valve simply because the diameter looks close.
2-Inch Camlock Fittings at a Glance
| Product | Camlock Type | Other End | Best For |
|---|---|---|---|
| Banjo Type B | Female cam coupler | Male NPT | Adding a quick female coupler to a female-threaded tank or pump port |
| Banjo Type A | Male cam adapter | Female NPT | Adding a male cam end to a male-threaded pipe or pump outlet |
| Banjo Type C | Female cam coupler | Hose shank | Building a removable hose end |
| Banjo Type D | Female cam coupler | Female NPT | Connecting to existing male NPT plumbing |
| Banjo Type F | Male cam adapter | Male NPT | Adding a male cam end to an existing female NPT port |
Camlock Types Are About End Combinations
The fastest way to choose is to name both ends of the fitting.
A Type A fitting has a male cam adapter on one side and female pipe thread on the other. A Type B has a female cam coupler with arms and male pipe thread. A Type C has a female cam coupler and a hose shank. A Type D has a female cam coupler and female pipe thread. A Type F has a male cam adapter and male pipe thread.
Those combinations matter more than brand or weight. If a water tank already has a male NPT outlet and you want a female cam coupler on it, Type D is the logical shape. If a pump has a female NPT port and you want a male cam adapter, Type F fits that layout.

The Banjo Type B is the most versatile starting point when a tank, pump, or pipe fitting presents a female 2-inch NPT port and you want a quick-connect female cam coupler on the outside. Screw the male NPT end into the equipment, then the female cam arms can accept a matching 2-inch male cam adapter whenever the hose or transfer line is connected.
That layout is especially useful for removable pumps and water-transfer hoses. It can make secure IBC-tank and pump connections, with the cam arms making repeated hook-up faster than threading a large hose fitting on and off.
The exact material and overall dimensions are uncertain. Fit deserves more attention than the material claim anyway. Some tote outlets do not use standard 2-inch NPT even when they look similar, so match the actual thread. Use appropriate thread sealing on the NPT side and rely on the camlock gasket—not thread tape—at the cam-and-groove joint.
Why It Works
- Female cam arms give you a fast removable connection.
- The male 2-inch NPT end fits equipment with a matching female pipe thread.
- The camlock gasket can create a clean water connection without tools each time you reconnect.
- The layout works well for pumps, IBC adapters, and temporary transfer hoses when the threads match.
What To Keep In Mind
- Exact material and secondary dimensions are uncertain.
- An IBC tote outlet is not automatically 2-inch NPT.
- Keep the cam gasket clean and replace it if it becomes cut, flattened, or hard.

The Banjo Type A reverses the Type B arrangement. It gives you a male cam adapter on one end and female 2-inch NPT threads on the other. That makes it useful when the existing pipe, pump, or valve presents a male NPT connection but the removable hose uses a female cam coupler.
The fitting is light and compact, which is useful on portable pumps and tank manifolds where large metal hardware would add unnecessary weight. Properly matched camlock components support quick water-transfer connections and reliable seals.
The exact material and dimensions are uncertain. Also remember that the female NPT side seals differently from the cam side. The pipe-thread connection needs the appropriate sealing method, while the male cam adapter seals against the gasket inside the mating female coupler.
Why It Works
- The male cam end mates with common 2-inch female cam couplers.
- Female NPT threads attach to a matching male pipe connection.
- The fitting works well as a pump or manifold adapter that stays installed between uses.
What To Keep In Mind
- Exact material and dimensions are uncertain.
- Match the actual male pipe thread before installation.
- A nominal 2-inch camlock and 2-inch pipe thread describe different surfaces on the same fitting.

The Banjo Type C is the most useful choice when you are building the end of a flexible transfer hose. The female cam coupler gives the hose a quick-release connection, while the opposite end is a shank that slides inside compatible hose and is secured with suitable clamps or another approved hose-retention method.
That means the fitting can remain attached to the hose permanently while the cam arms handle daily connection and removal. It is a natural fit for portable transfer pumps, tank-filling hoses, or temporary irrigation lines that get rolled up between uses.
The exact dimensions are uncertain. The key installation issue is the hose-to-shank seal. A leak at that joint usually points to the hose size, clamp, or clamping method rather than the camlock gasket. Severe freezing can also damage plastic-style couplers, so drain flexible transfer lines before cold storage.
Why It Works
- The hose shank creates a purpose-built end for a flexible 2-inch hose.
- Female cam arms make the hose quick to attach and remove.
- The fitting is useful for transfer-pump discharge and tank-filling lines.
What To Keep In Mind
- Exact dimensions are uncertain.
- Use a hose and clamp system sized for the shank.
- Drain water before freezing conditions to reduce stress on the fitting and hose.

The Type D fitting is useful when an existing valve, nipple, or tank adapter already has a male NPT thread and you want that point to become a female camlock connection. The female pipe thread screws onto the plumbing, while the cam arms accept a male cam adapter from the removable hose or pump line.
The coupler can provide a tight cam fit, smooth arm movement, and quick pump connections. This is a good arrangement when the threaded part stays fixed on the tank and the hose is the part you remove often.
The exact dimensions are uncertain. Keep the locking pins and arm hardware attached when the fitting is stored, and inspect the internal gasket before high-volume water transfer. A torn gasket can leak even when both arms close normally.
Why It Works
- Female NPT threads attach to a male pipe outlet.
- Female cam arms provide a fast hose connection after installation.
- The layout works well on fixed tank plumbing and spare transfer pumps.
What To Keep In Mind
- Exact dimensions are uncertain.
- Use the correct thread seal on the NPT side.
- Cam-arm locking pins can be lost if they are not tethered during field use.

The Banjo Type F gives you a male cam adapter and male NPT threads. It is the right shape when the tank, pump, or manifold has a female 2-inch NPT port and the removable hose ends in a female cam coupler.
Unlike Type B, there are no cam arms on this fitting. It stays as the male half of the quick connection, while the hose-side female coupler supplies the arms and gasket. That keeps the fixed equipment side simple and can reduce snagging when the hose is disconnected.
Its clearest role is connection geometry rather than a weight or pressure advantage. Match the male NPT thread to the equipment, tighten with an appropriate sealant method, and keep the cam surface clean so the mating gasket can seat properly.
Why It Works
- Male NPT threads fit a matching female pipe port.
- The male cam end provides a clean target for a removable female hose coupler.
- No cam arms remain on the equipment side when the hose is disconnected.
What To Keep In Mind
- Match the fixed port to a 2-inch NPT connection.
- Protect the exposed male cam surface from dirt and damage during storage.
- The mating female coupler is what contains the sealing gasket and locking arms.
How to Build a Camlock Connection
A complete camlock joint always needs a male adapter and a female coupler of the same nominal cam size. The female side contains the gasket and cam arms. Push the male adapter fully into the coupler, then close both arms evenly.
The pipe or hose end on each fitting is separate from the cam interface. Type A and D use female pipe threads. Type B and F use male pipe threads. Type C uses a hose shank. Choose those non-cam ends from the tank, pump, pipe, or hose already in the system.
Do not use the cam arms to pull badly misaligned piping together. The fittings should meet naturally before the arms close.
Camlock Fittings on IBC Totes
IBC totes often use large outlet valves that can accept camlock adapters, but the factory thread behind that adapter varies. Some valves use coarse buttress-style threads rather than NPT.
If the tote already has a male camlock adapter molded or threaded onto the valve, a matching female coupler may connect directly. If not, identify the tote outlet and use a purpose-built IBC adapter before adding the camlock fitting.
Forcing an NPT fitting onto a non-NPT tote valve can damage both pieces and still leak.
Camlock Gaskets and Leaks
The female cam coupler seals against a gasket. Keep that gasket clean, flat, and flexible. Sand, roof grit, and dried sediment can keep the male adapter from seating fully.
If a camlock leaks, first inspect the gasket and the mating adapter surface. Closing the arms harder will not fix a cut gasket or an adapter from a different size family.
The threaded side is a separate seal. A leak at the NPT joint needs to be corrected as a threaded plumbing connection, not as a camlock problem.
Cold Weather and Storage
Drain camlock hoses before freezing weather. Water trapped in a hose, coupler, or pump line can freeze and stress the fitting; an older coupler may crack after severe cold exposure.
Disconnect seasonal hoses, let them drain, and protect open male adapters with a compatible cap or plug when possible. Keeping dirt out of the joint also extends gasket life.
Common Camlock Problems
The Arms Will Not Close
The male adapter may not be fully inserted, the gasket may be displaced, or the parts may be different camlock sizes. Do not use excessive force.
The NPT Side Will Not Fit the Tank
The tank may use a different thread standard. This is especially common with IBC tote outlets. Identify the valve thread before adding an NPT fitting.
The Connection Leaks With Both Arms Closed
Inspect the gasket and male adapter surface. A worn seal, dirt, or damaged adapter can leak even when the arms are fully locked.
The Hose Leaks Behind a Type C Fitting
The problem is at the hose shank and clamp, not the camlock face. Check hose size and the retention method.
The Fitting Cracked After Winter
Trapped water and freezing conditions may have stressed the body. Drain seasonal water-transfer equipment before storage.
Frequently Asked Questions
What is the difference between Type A and Type B camlock fittings?
Type A has a male cam adapter with female NPT threads. Type B has a female cam coupler with male NPT threads. They solve opposite connection layouts.
Which camlock type connects directly to a hose?
Type C uses a female cam coupler on one end and a hose shank on the other, making it a common choice for building a removable transfer-hose end.
Are all 2-inch camlock fittings interchangeable?
The cam-and-groove ends should match the same nominal size, but the pipe threads, hose shanks, materials, and manufacturer tolerances still matter. The non-cam side must match your equipment separately.
Can I put a 2-inch camlock on an IBC tote?
Yes with the correct tote adapter or factory cam outlet. Do not assume the tote valve uses 2-inch NPT simply because it is near that size.
Do camlock fittings need thread tape?
Only on compatible threaded joints when the fitting instructions call for it. The camlock face itself seals with a gasket, not thread tape.
Why does my camlock leak even when the arms are tight?
A dirty, damaged, hardened, or incorrect gasket is a common cause. Also check that the male adapter is fully seated and that both parts are the same nominal cam size.
For the large shutoff before a removable hose, ball valves for rainwater tanks compare serviceable PVC valve options. If the tank does not yet have a threaded outlet, bulkhead fittings for water tanks cover the wall connection first. For IBC-specific factory valve threads, IBC tote adapters explain the conversion step before camlocks. If the removable hose feeds a pump, transfer pumps for rainwater cover the flow side of the setup.
