HEX HEAD PLUG (ASME B16.11)

HEX HEAD PLUG

ASME B16.11

Is a standardized pipe fitting designed with a hexagonal head for easy installation and removal. This plug serves as a reliable and secure closure for threaded openings in piping systems.

Its hexagonal design allows for simple tightening and loosening with standard tools, ensuring a leak-proof seal. The ASME B16.11 compliance ensures compatibility with other components, providing a versatile and efficient solution for sealing threaded connections in piping systems.
