Continue to hold the hose and coupler sleeve until all air is fully exhaustedAfter the line is fully exhausted, you are able to safely separate the nipple from the couplerSafety notesIt 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 failureWARNING: This product contains a chemical known to the State of California to cause birth defects or other reproductive harm.
