The ASME B16.11 Stainless 2000# Threaded Couplings are high-pressure fittings used to join or extend pipes. Full Couplings connect two pipes, while Half Couplings are used for branching or vessel nozzles. Forged from grades like 316L or 316Ti, they offer superior corrosion resistance and high-pressure integrity. Featuring precision NPT or BSP threads, they enable secure, weld-free assembly. Rated for 2000 PSI, these are essential for chemical, offshore, and pharmaceutical systems.
