Camlock Fittings

Aside from the cost-effectiveness, our Camlock Fittings can provide you the benefit as below:

• High Durability: Camlock fittings are available for a variety of material types, which allow to maximize the durability for each specific project or application.
• Easy to use: Camlock fittings are designed to easily connect or disconnect to the hoses or pipes, you can install it by using hands without any tool.
• Versatile application: It is applicable to most of the industry which uses water, liquids and gases.
• Reliable: Different materials would be able to withstand different temperatures and working pressure.

There are three types of commonly used material, which are aluminium (Al), stainless steel (SS316), and brass. Each of the material types would show its distinct characteristics and you may select the type which best suits your system.

Aluminium (Al): usually lightweight, it is an economical option to substitute some costly fittings. It is commonly applicable for water, hydraulic oil, slurry and dry powder and petroleum products as it has a good chemical resistance and abrasion resistance. Aluminium camlock are widely used in impurity pumps, general pumps, transfer pumps, IBC and storage tanks. Its working pressure depends on the temperature and size of the fittings.

Stainless Steel (SS316): high durability and strength, it can withstand high temperatures and is highly resistant to corrosion by chemicals or liquids. Stainless steel camlocks are commonly used in the food and sanitary field. The strong resistance to most chemicals and liquids all maintain a glossy appearance. It can provide a longer service life and does not contaminate the medium being transported, however it is much more expensive when compared to other materials.

Brass: similar to stainless steel, brass material has high resistance to damage and corrosion as stainless steel, however, brass fittings are more suitable for the shipbuilding industry as it can function well with water, coolant, gasoline, hydraulic oils, and petroleum. However, the brass camlock fittings are softer and easier to thread if compared to stainless steel. The size available is from 1/2" to 4" inch.

Below table show the maximum allowable working pressure (PSI) of cam and groove couplings:

When choosing a proper Camlock Fittings, it is important to consider the chemical compatibility of the process fluid and process temperature. The products that we provide are made according to the Mill Spec to ensure that the male adapter and female cam coupler mate correctly.

Cam & Groove coupling is suitable for most industries, including manufacturing, agriculture, oil gas, pharmaceutical, et cetera. It is a versatile product as the no threads features allow connecting the half coupling together without causing damage or dirt to the system, thus, it is recommended for a dirty environment. Also, it is particularly suitable for situations that require replacing the hoses frequently, for example, petroleum and industrial chemical trucks.

No, there are a variety of Camlock Fittings. The fittings we provide starting from type A to F, each fitting having a different type of connection.

Besides, Camlock Fittings are able to work at a maximum pressure of 250 psi. Nonetheless, the working pressure is affected by the valve body:

The camlock fittings have a variety of specifications to fit in each specific project requirement. You may consider the several fields of information required by your system or project application.

• Size (outer diameter)
• Temperature range
• Application
• Material
• Pressure rating
• Connection type

The Camlock Fittings include accessories such as pins, rings, handles and pins. The O-ring material is critical to identify the overall temperature range of the fittings. These are the O-ring materials that we offer:

1. NBR (Buna N)
NBR is the standard sealing material for camlock coupling. The synthetic rubber is chemically resistant and has high temperature capability against neoprene. It is resistant to oil-based hydraulics fluid fats, animal and vegetable oils, grease, water, air and flame retardants.

2. EPDM
Another standard sealing material in the polypropylene camlock couplings. EPDM rubber is resistant to ozone, heat, steam, strong acid, alcohol, and alkali. Nonetheless, it is not applicable to grease, oil and aromatics.

3. Viton
It is best suited in most corrosive industries as Viton has great resistance to mineral oils, aromatic hydrocarbons, greases and special chlorinated hydrocarbons, gasoline, diesel fuel, and silicone oil. It can effectively withstand temperature, weathering and gas permeability. However it is not suitable for anti-amine, ester, steam or low temperature environments.

4. PTFE (Teflon)
It can withstand high temperatures and has good resistance to almost all chemicals. Its flow capacity is limited, so rubber fillers must be used. The choice of filler depends on the application.

Type C: Hose Shank x Female Coupler SS316

The assembly of a Camlock Fittings includes a male groove adapter and a female coupler. As mentioned above, you can install the fittings by hand. In order to ensure the tightness of the seal, you can depress the cam arms and compress the coupler gasket. The fittings are mainly to avoid loosening due to vibration and accidents breakage.

It is easy and quick to install Camlock Fittings. The design is intended to provide fixed and leak-proof connections for hoses and pipes. In order to ensure the effect of fluid transfer, you can refer to the following steps when connecting a set of camlock fittings:

• Pull back the lock above the cam handle horizontally and at the same time remove the handle from the coupler body to open the coupler.
• Place the adaptor plug into the coupler.
• Close the coupler by rotating the cam handle toward the coupler body. The male and female fitting is locked when the camlock handles are closed. The female coupler is fully sealed to the system.

To disconnect camlock fittings, you can refer to the following steps:

• The hose coupling connection is depressurized before fitting disassembly. Open the female coupler by pulling back both sides locking lever above the cam handlers while rotating the handles opposite position from the coupler’s body.
• Take away the adaptor from the coupler.
• Rotate the handles towards the coupler’s body and lock the coupler when it is not in use to protect it from damage.

European Standard: Our Camlock Fittings comply with EN 14420-7 European Standard. The European Standard EN 14420-7 has been prepared by CEN/CT 218 “Rubber and plastics hose and hose assemblies” and was approved by CEN on 30 September 2004. It is applicable to Camlock fittings manufactured in accordance with the Mil Certification.
