NGT and 25E Tapered Threads
KEY FEATURES:
- Fill the high-pressure port (347, 680, or 701) to
4500PSI; gas is delivered through the 3000PSI outlet
(346, 580, or 540) at 700-1000PSI. - Regulator is cycle-tested to exceed typical cylinder life,
ensuring long-term durability. - Dual outlets support both lower and higher pressures from
the same cylinder. - Copper beryllium spring ensures compatibility with
oxygen and breathing air mixtures. - 3000PSI outlet protected by a secondary 2800-3000PSI safety device.
- Robust forged components and double O-ring seals provide superior
strength and leak protection in ultra-high-pressure applications. - No special adapters needed for filling; easy operation at all pressure levels.
- 100% leak tested, meeting and exceeding CGA V9 and ISO 10297
standards including stringent adiabatic oxygen compressing testing. - Valves are bagged for cleanliness in all gas services.
- Unitized plug with hex and threads for easy installation;
