Dixon DF-Series Pneumatic Female Threaded Plugs are made from solid steel and have a maximum pressure rating of 500 PSI. Safety Note: 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 in. 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.
