Specifications for Variant SKU: 4VF4-SS Dixon
Series: V-Series
Shape (Orientation): Straight
Ends Configuration: 1/2in Female V-Series QD Interchange, 1/2in Female NPTF
Material(s): 316 Stainless Steel
Seal Material(s): Buna-N/Nitrile Rubber
Compatibility & Interchange:
  • Interchangeable to MIL-C-51234
  • Interchangeable with Snap-Tite H/IH Series and Faster TNV
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.
Seal Components:
  • Nitrile seals are standard, providing a temperature range of -40°F to 250°F (-40°C to 121°C).
  • All couplers incorporate a PTFE anti-extrusion ring to protect the seal components from dynamic impulse damage.
  • 1/4" to 1" valve seals are crimped in place to maintain integrity during excessive flow conditions and pressurized connection.
  • 1-1/4" to 2" valve O-rings are retained by a uniqueseal-groove profile and are field replaceable.
