Dixon Valve T-series steel high pressure ball interchange fitting nipple. Machined components are manufactured using solid steel bar stock. Chrome steel ball valve is mechanically seated to improve low pressure sealing performance. Steel nipples are machined from solid high strength steel bar stock. Steel componentry is plated using ROHS Compliant Trivalent Chrome. 1.56 inches length. 10000 pounds-per-square-inch. Urethane seal is standard in ball valve couplers and provides resistance to extrusion when subjected to high pressure - temperature range -40 degree F to +180 degree F -40 degree C to +82 degree C). Nitrile seals are standard in poppet valve couplings, providing a temperature range of -40 degree F to +250 degree F -40 degree C to +121 degree C).
