How it works

• To disconnect, begin by holding the hose on the nipple side with three of your fingers, leaving your thumb and index finger free
• Grab the sleeve with your thumb and index finger and begin to pull the sleeve towards the palm of your hand
• After pulling the sleeve, the nipple will move out of the coupler slightly. Continue to hold the hose and coupler sleeve until all air is fully exhausted
• After the line is fully exhausted, you are able to safely separate the nipple from the coupler

Safety notes

• 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
