Camlock coupling

A camlock coupler (also referred to as cam lever couplings or cam and groove couplings) is a type fitting that allows quick connect and disconnect of components.

They are sometimes used in place of unions. They are faster to open and close, but usually rated for less pressure than unions.

Camlock couplings usually exist as a threaded fitting.

It is used mostly on combustion cannons as a quick means to change between barrels, to hold burst disks, and for breech loading.

A popular camlock coupling is available from BCARMS.
