DESCRIPTIONS
Interchange Data:
– Interchangeable to MIL-C-51234
– Snap-Tite H/IH and Faster TNV/TNL
Materials:
– Machined components are manufactured using solid steel, brass, or 316 stainless 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 machined from high-strength steel and induction hardened.
– Tubular ‘TV’ valves are constructed from steel bar stock and are designed for optimum performance in pneumatic applications.
Seal components:
– Nitrile (Buna-N) seals are standard, providing a temperature range of -40oF to +250oF (-40oC to +121oC).
– All couplers incorporate a PTFE anti-extrusion ring to protect the seal components from dynamic impulse damage.
– 1/4″ to 1″ valve seals are crimped in place to maintain integrity during excessive flow conditions and pressurised connection.
– 11/4” to 2″ valve O-rings are retained by a unique seal-groove profile and are field replaceable.

Note:
– Air flow data is presented using a coupler with a ‘TV’ valve and unvalved nipple. This configuration provides the optimal performance for pneumatic applications.
– 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 operating pressure must be divided by two(2) to ensure a 4:1 safety factor during system operation.
