Steel componentry is plated using ROHS Compliant
Trivalent Chrome.
•
Steel coupler sleeves are hardened to resist deformation
and maximize service life.
•
Steel nipples are hardened to provide heavy duty
performance and resist brinneling.
•
Nitrile (Buna-N) seals are standard, providing a temperature
range of -40°F to +250°F (-40°C to +121°C).
•
Couplers have a PTFE Anti-Extrusion ring.
•
Valve seals are crimped in place to maintain integrity during
