Dixon Valve & Coupling
Hydraulic Coupling: TR-Series European Interchange Coupler (Female Threads)

Specifications for Variant SKU: 3TRF3 Dixon
Series:	TR-Series
Shape (Orientation):	Straight
Ends Configuration:	3/8in Female TEMA European QD Interchange, 3/8in Female NPTF
Material(s):	Steel
Seal Material(s):	Buna-N/Nitrile Rubber

Compatibility & Interchange:	TEMA European Interchange TEMA 3800, 5000, 7500, 10000 Series CEJN Series 525
Construction:	Machined components are manufactured using solid steel bar stock. Stainless steel balls, retaining rings, and springs maximize corrosion resistance and extend service life. Steel componentry is plated using ROHS-compliant trivalent chrome. Steel coupler sleeves are hardened to resist deformation and maximize service life. Steel plugs are hardened to provide heavy-duty performance.
Seal Components:	Nitrile seals are standard, providing a temperature range of -40°F to 250°F (-40°C to 121°C). Couplers have a redundant O-ring sealing system (dual O-rings with inner PTFE back-up ring). Valve seals are crimped in place to maintain integrity during excessive flow conditions and pressurized connection.
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
