  • CEJN Series 525
Construction:
  • Machined components are manufactured using solid steel 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.
  • Steel plugs are hardened to provide heavy-duty performance.
Seal Components:
  • Nitrile seals are standard, providing a temperature range of -40°F to 250°F (-40°C to 121°C).
  • Couplers have a redundant O-ring sealing system (dual O-rings with inner PTFE back-up ring).
  • Valve seals are crimped in place to maintain integrity during excessive flow conditions and pressurized connection.
