Plugs

A full range of black carbon steel solid plugs to ASME B16.11 is available here on our website, this includes square and hexagon head plugs in sizes 1/8” (6mm) – 4” (100mm) 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 plugs come with male BSPT threads to ISO 7-1 (BS EN 10226) or NPT male 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.
