Dixon U.S.A.
DESCRIPTIONS
Interchange Data:
– Interchangeable with Snap-Tite 71-Series
Materials:
– Machined components are manufactured using solid steel bar stock.
– Stainless steel balls, retaining rings, and springs maximise corrosion resistance and extend service life.
– Steel componentry is plated using ROHS Compliant Trivalent Chrome.
– Steel coupler sleeves are hardened to resist deformation and maximise service life.
– Steel nipples are hardened to provide heavy duty performance.
Seal components:
– Nitrile (Buna-N) seals are standard, providing a temperature range of -40oF to +250oF (-40oC to +121oC).
– All couplers and nipples incorporate PTFE or TPC-ET anti-extrusion rings to protect the seal components from dynamic impulse damage.

Note: Minimum burst pressure ratings were established under laboratory conditions using 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.
