Lincoln Pneumatic Coupling

Lincoln pneumatic couplings, also known as pneumatic quick couplers or air couplers, are primarily used to connect compressed air tools, hoses, or other pneumatic devices to a compressed air supply,

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.
