Dixon Valve high pressure ball interchange fitting coupler. Machined components are manufactured using solid steel bar stock. Chrome steel ball valve is mechanically seated to improve low pressure sealing performance. Steel componentry is plated using ROHS Compliant Trivalent Chrome. 2.58-inches length. 10000 pounds-per-square-inch pressure. 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).
