Providing a temperature range of -40°F to 250°F (-40°C to 121°C). Stainless steel retaining ring and spring maximize corrosion resistance and extend service life on the 1 piece sleeve. 2-Piece Sleeve has a phosphor bronze spring. Steel componentry is plated using ROHS Compliant Trivalent Chrome.
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.
Additional Information:	For a selection guide, cross reference tables, safety info, fluid compatibility, and other general info, please see: Dixon Valve Quick Disconnect Guide.PDF
