dixonvalve.comST-Series Hydraulic Couplings
Interchange Data:
•
Interchangeable with Snap-Tite 71-Series
Materials:
•
Machined components are manufactured using solid steel
or 316 stainless 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 nipples are hardened to provide heavy duty
performance.
•
Nitrile (Buna-N) seals are standard, providing a temperature
range of
-40°F
to
+250°F
(
-40°C
to
+121°C
).
•
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 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.
