The ASME B16.11 Stainless 2000# Threaded Reducing Coupling is a forged fitting designed to connect two pipes of different diameters in high-pressure systems. Forged from grades like 316L or 316Ti, it ensures superior resistance to chemical corrosion and thermal stress. Featuring precision NPT or BSP threads at both ends, it enables secure, weld-free size transitions. Rated for 2000 PSI, it is a compact solution for instrumentation and process lines in pharmaceutical, marine, and chemical industries.
