Compatibility & Interchange:	Truflate Automotive Interchange Parker 10 Series, Rectus 55KM and Tomco A2100/PT400
Construction:	Machined components are manufactured using solid bar stock. Stainless steel balls, retaining rings and springs maximize corrosion resistance and extend service life. Nitrile (Nitrile Rubber) seals are standard. (temperature range of -40°F to 250°F (-40°C to 121°C)) Steel componentry is plated using ROHS Compliant Trivalent Chrome. Steel sleeve and steel tubular valve.
Safety Notes:	Operating pressure for couplings utilizing hose barb connections may be dramatically reduced to that of the hose rating and/or hose end connection combination. Consult hose manufacturer's catalog for hose end connection ratings. If in doubt, test under controlled conditions for suitability to application. Dixon cannot assume liability for misapplication of production resulting in equipment down-time, lost production, and/or personal injury including death. 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.
