6. What are the different types of Camlock Fittings?
There is a variety of Camlock Fittings ranging from Type A to Type DP. The table below shows the full description by Camlock type and connection type.
7. Guide to Camlock Fittings O-ring seal material selection
Camlock fittings O-ring seal material is key to determine the overall temperature range of the Camlock fittings. Below are the O-ring seal materials that we offer:
NBR: It is a commonly used seal material for Camlock fittings. Nitrile is a synthetic rubber that improved chemical resistance and temperature capabilities to neoprene. NBR material seal offers good resistance to oils and solvents, aromatic and aliphatic hydrocarbons, petroleum oils, and gasoline's as well as animal fats and lacquer solvents. Its poor resistance against strong oxidizing agents, chlorinated hydrocarbons, ketones, and esters.
EPDM: its offers great resistance to ozone, heat, steam, strong acid, and alkaline. However, It is not recommended for use in oils, solvents, and aromatic hydrocarbons.
Viton: it is called fluorinated hydrocarbon seal material offers outstanding resistance against acid, aliphatic hydrocarbons, oils, gasoline, and many corrosive industrial applications. This material is excellent for resistance to temperature, weathering, and gas permeability.
However, it is not appropriate for use against amines, esters, ketones, steam, or low-temperature service.
PTFE: this seal material is resistant to nearly all chemicals, other than that PTFE also has good temperature capabilities. It has very limited flow capabilities which required the use of a rubber filler.
As PTFE seal material is slightly porous, the choice of filler is dictated by the application medium or temperature.
8. How to measure dimensions of Camlock Fittings?
It's relatively easy to measure Camlock fittings, for instance, if the hose shank or threaded end is 2” then the Camlock fittings would be known as 2” Camlock fittings.
Camlock fittings sizes are measured by using the Outside Diameter (OD) of the adapter head or the Inside Diameter (ID) of the coupler.
Examples of how to measure the fitting size are as depicted in the images below.
9. How to disconnect Camlock Fittings?
The disassembly commonly comprises a male groove and a female coupler.
For disconnection of adaptor from the coupler, firstly depressurize the connection of the Camlock fitting.
Pull up the levers to above of cam handle then remove the adaptor from the coupler.
Whenever adaptors or couplers are not in use, it's best to connect them to a dust cap or dust plug to prevent them from damage.
HOW TO INSTALL A CAMLOCK FITTING
The assembly commonly comprises a male groove and a female coupler.
Extend the handles of the coupler outwards and insert the appropriate size male groove adapter into the female coupler.
Close both handles at the same time ensures both halves are firmly fit together.
Close both handles at the same time ensures that the grooved adapter is pulled down and fit firmly onto the seal making a leak-proof assembly for the safe transfer of liquids.
