Dixon DF-Series Pneumatic Automatic Female Threaded Couplers are made from solid brass and have stainless steel balls, retaining rings and springs to maximize corrosion resistance and extend service life. Maximum pressure rating of 500 PSI (Brass Coupler & Steel Plug).
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.
