Stainless steel reducing hex bushings provide compact, leak-free pipe size transitions in threaded and high-pressure piping systems. Engineered to meet ASME B16.11 and MSS-SP standards, these forged fittings handle pressure classes from 3000# to 6000# across process piping, instrumentation lines, skid assemblies, and demanding industrial fluid applications.


A hex bushing is a compact fitting designed to connect two pipes or components of differing diameters. It features external male threads, internal female threads, and an integrated hexagonal head. The hex head provides an accessible surface for tightening with standard pipe wrenches, ensuring tight, leak-free joints in threaded fluid and gas piping connections.
