Reducing Couplings

Reducing Couplings

Galvanised forged carbon steel reducing couplings to ASME B16.11 are available here on our website in sizes up to 4” (100mm) x 3” (80mm) nominal bore. These pipe fittings are all forged from HDG galvanised ASTM A105N carbon steel and conform to the ASME B16.11:2016 and BS 3799:1974 standards.

Our ASME B16.11 couplings come either BSPT threaded to ISO 7-1 (BS EN 10226) or NPT threaded to ASME B1.20.1, they’re manufactured in Europe and come with 3.1 test certificates. These forged fittings are 3000lb/psi (206 bar) pressure rated and generally used in high pressure/temperature installations with ASTM A106 seamless steel tube.
