All couplers have a high concentration of locking balls to reduce incidents of brinneling during operation.
Industrial Interchange couplers have a sleeve-guard 'Lip' to reduce the risk of accidental disconnection
while in service.
Industrial Interchange quick couplers are available in a variety of material configurations.

It is important to be safe when installing quick disconnect couplings into a pneumatic circuit. Never install a pneumatic
coupling directly into an air tool, use a piece of hose that is at least 18" long, between the tool and the coupling,
to prevent damage to the coupling. To protect the operator, safety devices, such as a Safety Check Valve and Safety Cable,
should be installed in case there is a hose or coupling failure.
