Hexagon Reducing Bushes

A full range of black carbon steel hexagon reducing bushes to ASME B16.11 is available here on our website, this includes sizes up to 4” x 3” nominal bore. These pipe fittings are all forged from black (self-colour) ASTM A105N carbon steel and conform to the ASME B16.11:2016 and BS 3799:1974 standards.

Our ASME B16.11 reducing bushes come male/female threaded with BSPT threads to ISO 7-1 (BS EN 10226) or NPT threads to ASME B1.20.1, they’re manufactured in Europe and come with 3.1 test certificates. These forged fittings are 6000lb/psi (413 bar) pressure rated and generally used in high pressure/temperature installations with ASTM A106 seamless steel tube.
