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.
