Series:	K-Series
Shape (Orientation):	Straight
Ends Configuration:	1/2in Female ISO-A QD Interchange, 1/2in Female NPTF
Material(s):	316 Stainless Steel
Seal Material(s):	Buna-N/Nitrile Rubber

Compatibility & Interchange:	Interchangeable to ISO7241 Series 'A' Parker 6600-Series, Danfoss/Aeroquip/Eaton FD56 (5600) Faster ANV, Hansen HA 15000, Safeway S56-Series
Construction:	Machined components are manufactured using solid 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. Nitrile seals are standard, providing a temperature range of -40°F to 250°F (-40°C to 121°C). Couplers have a PTFE Anti-Extrusion ring. Valve seals are crimped in place to maintain integrity during excessive flow conditions and pressurized connection.
Features:	Poppet style shut-off valve.
