CAMLOCK FITTINGS
Camlock fittings (also known as cam and groove couplings) are the fastest, most cost-effective way to connect hoses and pipes without tools. We supply Australia's widest range of Aluminium, Stainless Steel, Polypropylene, and Nyglass camlocks from ½" to 6" (with 8" available on request) — all manufactured to MIL-A-A-59326 specification for guaranteed compatibility with existing systems.

Camlock Fitting Specifications
HOW CAMLOCK FITTINGS WORK
Camlock fittings consist of two parts: a male adapter (grooved end) and a female coupler (receiving part with cam arms). They require no tools to operate and can be connected or disconnected in seconds.
Step-by-step connection process:
- Insert — The male adapter is inserted into the female coupler until it seats fully against the internal gasket.
- Lift — The female coupler arms will rise slightly as the adapter is pushed home.
- Close — The female coupler arms are then closed by applying hand pressure in towards the coupler body until they lock flat against the fitting.
- Secure (optional) — For extra precautions, safety pins can lock the arms in place. This is recommended when operating near maximum pressure ratings, transporting valuable materials, or working in high-vibration environments.
Inside the female coupler, a gasket is recessed in place. When the adapter is inserted, the cam arms compress the adapter against this gasket, creating a tight, leak-proof seal.
MATERIALS
- Aluminium Camlock - best for: Lightweight, non-corrosive fluids and general-purpose applications.
- Stainless Steel 316 Camlock - best for: Highly corrosive environments, marine, food grade.
- Stainless Steel 304 Camlock - best for: General corrosion resistance at a lower cost than SS316.
- Polypropylene Camlock - best for: Aggressive chemicals at low-to-moderate temperatures.
- Nyglass (Nylon + 30% Glass Fibre) Camlock - best for: Lightweight, chemical-resistant, high-strength non-metal option.
GASKET MATERIAL
All our metal camlocks are supplied standard with Buna-N (Nitrile) gaskets. The Poly camlocks come standard with EPDM gaskets for better resistance to acid and compatibility with water.
- Buna-N (Nitrile)
- EPDM
- Viton
- PTFE (Teflon) special order.
Gasket selection tips:
- Oil, fuel or petroleum-based fluids? Choose Buna-N (standard with metal camlocks)
- Water, acids or caustic solutions? Choose EPDM(standard with polypropylene)
- High temperatures or harsh chemicals? Choose Viton(premium option)
- Food, pharmaceutical or highly corrosive? Choose PTFE (special order)
DIFFERENT SIZES
For Aluminium and Stainless Steel Camlock Fittings we have sizes starting from ½” up to 8”. Polypropylene is offered in sizes starting from ½” up to 4”. All our ½” couplings are manufactured with 2 handles for better operation.
PRESSURE RATING
According to the Mil Spec, the cam and groove hose fitting is rated to operate at 150 psi. This may not be the case in sizes higher than 4" where operating pressures are generally lower. Please see technical specifications page for the operating pressure for each size.
CAMLOCK FITTING THREADS
- All threads are BSP
- Female threads are BSPP (Parallel)
- Male threads are BSPT (Tapered)
British Standard Pipe Threads (BSP) are widely used in most commonwealth countries. Threads have a pitch angle of about 55 degrees. They are designed to thread onto a pipe and tighten. Hose shanks are available on the Type C and Type E for a direct fit into the hose.

APPLICATIONS
Used across industry, primarily where liquids and powders are moved from one location to another. For example, Chemical, Pharmaceutical, Cleaning, Military and Government Bids, Fuel & Oil, Food and Beverage, Water, Paints & Dyes, Adhesives, Agriculture, Air Conditioning to mention a few. They are commonly used on hoses, pipes, pumps & tanks, tankers etc.
* Cam and Groove Fittings are not be used with compressed air or steam *
FREQUENTLY ASKED QUESTIONS
1. What types of camlock fittings are available?
We offer a full range of camlock types to suit different connection needs. The main types include Type A (male adapter, female thread), Type B (female coupler, male thread), Type C (female coupler, hose shank), Type D (female coupler, female thread), Type E (male adapter, hose shank), Type F (male adapter, male thread), Type DC (dust cap), and Type DP (dust plug). See The Type of Camlock Explained section above to help you choose the right one.
2. Can I connect camlock fittings from different manufacturers?
Yes, compatibility is guaranteed as long as the fittings are manufactured to the same standard specification (MIL-A-A-59326, formerly MIL-C-27487). All our camlock fittings are made to this Mil-Spec standard, ensuring they are fully interchangeable with other brands that also meet this specification, such as Dixon, PT Couplings, and Banjo.
3. Are camlock fittings leak-proof?
Yes, camlock fittings are designed to provide a leak-proof seal when used correctly. The seal is achieved by the cam arms compressing the male adapter against a rubber gasket inside the female coupler. However, the seal's integrity depends on using the correct gasket material for your application, ensuring components are not worn or damaged, and making a proper connection.
4. Do camlock fittings require tools to install or operate?
The cam and groove connection itself requires no tools. You simply insert the adapter into the coupler and close the cam arms by hand. However, installing the fitting onto a pipe may require standard pipe wrenches, and a hose shank will need a hose clamp or a crimping tool.
5. How do I choose the right material for my camlock fitting?
The right material depends on your application. Aluminium is ideal for general-purpose, lightweight use. Stainless Steel 316 is best for highly corrosive environments and food-grade applications. Polypropylene is excellent for aggressive chemicals at lower temperatures, and Nyglass is a strong, lightweight non-metallic option. For detailed guidance, please see the Material Selection Guide section above.
6. What is the maximum operating pressure for a camlock fitting?
Camlock fittings manufactured to the Mil-Spec standard are generally rated up to 150 psi (10 bar). It's important to note that this rating can be lower for sizes above 4 inches. Always refer to our Technical Specifications page for the specific pressure rating for your required size and material combination.
7. Are camlock fittings safe to use with compressed air or steam?
No. Cam and groove fittings must never be used with compressed air or steam applications. They are designed for liquid and powder transfer, not for gas or steam service. Using them in these applications is a serious safety hazard and can lead to fitting failure and severe injury.
8. How often should I replace the gasket in my camlock fitting?
Gasket replacement frequency depends on usage and application. For light-duty applications, gaskets can last 2-3 years. In high-cycle or chemical applications, we recommend replacing them every 6-12 months. Always replace the gasket at the first sign of cracking, hardening, or loss of elasticity.
9. Are camlock fittings suitable for food-grade applications?
Yes, stainless steel camlock fittings (both SS304 and SS316) are suitable for food process applications. We recommend using PTFE or food-grade silicone gaskets for these applications. All our stainless steel fittings can be electro-polished for sanitary requirements.
10. What thread type do your camlock fittings use?
All our camlock fittings use British Standard Pipe (BSP) threads. Female threads are BSPP (Parallel) and male threads are BSPT (Tapered). This is the standard thread type used in Australia and most Commonwealth countries. For customers with specific requirements, we also currently supply NPT (National Pipe Thread) threads on select Stainless Steel Camlock fittings in certain sizes and Types.
