The air hose connector is composed of a cam coupling. The ball bearing is pressed into the groove processed into the half of the male connector, and the female connector is fixed to the male connector assembly using a spring-assisted sliding ring. Sliding the lock ring makes it easy to loosen the air hose joint, thereby loosening the ball bearing and the male joint so that it can be ejected from the coupling. Machinists and #039; pneumatic wrenches and other tools that use compressed air usually have quick couplings. One of the many benefits of using air compressors and air tools is that many different air tools can be easily and quickly replaced. This is achieved through the use of air hose connectors. By installing the connector to the end of the air hose, the connector can be replaced repeatedly within a few seconds without losing the air pressure in the compressor... less
