  • 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.

Minimum burst pressure ratings were established under laboratory conditions using a Static Burst Unit (SBU).
For high impulse applications and to meet Det Norske Veritas (DNV) compliance, the burst pressure must be divided by four (4) to ensure a 4:1 safety factor during system operation.
