Compatibility & Interchange Data

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 (Nitrile Rubber) seals are standard
  • Incorporates PTFE anti-extrusion rings to protect seal components from dynamic impulse damage.

Note

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.
