Polypropylene camlock fittings are primarily used for low-pressure situations, such as discharge or suction hoses of fire-fighting pumps or IBC containers and any other application where you need a quick connect/disconnect feature. The black cam locks offer excellent chemical resistance for most corrosive solvents and aggressive chemicals, though they may not be as durable as nylon, stainless steel, or aluminium cam locks.
When you choose polypropylene couplings, the cam pins and arms are made of stainless steel. It is essential that employees who work with them be careful while attaching or crimping the coupling, as it can be damaged, especially as it wears.
The couplings are easy to install because all you have to do is put the adapter and coupler together (making sure they are the same size) and push the cam arms down at the same time using even pressure.
You should not use polypropylene fittings with gas or compressed air. Along with such, the accessories, such as plugs and dust caps, shouldn’t be used in high-pressure applications.
While it may seem like other materials are more suitable, polypropylene does offer many benefits. For one, it is resistant to most chemicals, and for another, it is less expensive than other options. Therefore, you can purchase some to determine if they’re right for your needs without spending too much.
The quick connect/disconnect feature requires no tools and also ensures that you can connect or disconnect the coupling quickly and easily.
It should be noted that, as the temperature of the liquid increases, the operating pressure of polypropylene decreases significantly. Along with such, the working pressure depends on the temperature and size of the coupling and hose. The temperature range (for water) is between -15 degrees Fahrenheit and 200 degrees Fahrenheit, giving you a good indication of how to use them in your applications.
