SQUARE HEAD PLUG (ASME B16.11-2016)

SQUARE HEAD PLUG

ASME B16.11-2016(Revision of ASME B16.11-2011)

Is a standardized pipe fitting, revised from ASME B16.11-2011, featuring a square-shaped head for easy and secure closure of threaded openings. This plug ensures a reliable and tight seal, effectively preventing leakage in piping systems.

The square head design allows for a sturdy grip, enabling effortless installation and removal. With threaded or socket-weld end connections, it ensures simple installation and compatibility with other ASME B16.11 compliant components, providing a versatile and efficient solution for sealing threaded connections in piping systems.
