Hydraulic Coupling: HTZ-Series ISO16028 Connect Under Pressure Flush Face Coupler (Female Threads)

For use with HT or HTE series plugs.
Specifications for Variant SKU: 4HTZF4 Dixon
Series: HTZ-Series
Shape (Orientation): Straight
Ends Configuration: 1/2in Female ISO-16028 Flush Face QD Interchange, 1/2in Female NPTF
Material(s): Steel
Compatibility & Interchange:
  • Interchangeable to ISO16028.
  • For use with HT or HTE series plugs.
  • Connectable with trapped pressure on HTZ half only.
Construction:
  • Machined components are manufactured using solid steel or 316 stainless steel 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.
  • Steel plugs are hardened to provide resistance to brinelling during impulse service.
Seal Components:
  • 1/2"plugs have molded polyurethane valve seals, with a temperature range of -65°F to 212°F (-54°C to 100°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 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.
