Quantity

Specifications for Variant SKU: 4HTRB4 Dixon
Series:	HT-Series
Shape (Orientation):	Straight
Ends Configuration:	1/2in Female ISO-16028 Flush Face QD Interchange, 1/2in Male O-Ring Face Seal
Material(s):	Steel
Seal Material(s):	Buna-N/Nitrile Rubber

Compatibility & Interchange:	Interchangeable to ISO16028. Conforms to ISO16028 interchange standard interchangeable with Danfoss/Eaton/Hansen FF, Parker FEM, Snap-tite 74, Faster FFH/2FFN/2FFI, Stucchi A/FIRG and Holmbury HQ/A/FIMC.
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 zinc nickel for corrosion resistance. Steel coupler sleeves are hardened to resist deformation and maximize service life.
Seal Components:	1/4", 3/8", 1/2", 3/4", and 1" plugs have molded polyurethane valve seals, with a temperature range of -65°F to 212°F (-54°C to 100°C). 5/8", 1-1/2", and 2" plugs have Nitrile-energized PTFE valve seals, with a temperature range of -40°F to 250°F (-40°C to 121°C). Couplers have a polyurethane valve stem O-ring, with a temperature range of -65°F to 212°F (-54°C to 100°C). Ancillary coupler and plug seals are Nitrile (Nitrile-N), with a temperature range of -40°F to 250°F (-40°C to 121°C). PTFE or TPC-ET anti-extrusion ring protects main coupling valve seal from dynamic impulse pressure damage.
Features:	High flow performance, compact profile. Easily rebuildable! High strength laser-cut valve guide maximizes valve stability while minimizing flow restriction. Improved sealing system incorporates a high performance molded polyurethane or O-ring energized PTFE valve seal. DORS (dual opposing retention spheres) retention system prevents valve stem ejection during surge flow and pressure spike conditions.
