A G.I. socket, known in American usage as a coupling, is a short cylindrical fitting with a female thread through its full length or from each end. It joins two male-threaded pipes end to end, or connects a pipe to a male-threaded valve, pump or tank boss. Malleable iron sockets in EN 10242 are pattern M2, often with a reinforcing band at each end. Unlike a union, a socket cannot be undone without turning the pipe.
Hamza Fasteners stocks galvanised sockets from 1/4 inch to 4 inch, threaded BSPT as standard and NPT on request. They are used to extend water supply lines, repair runs, and make up pipe lengths on site in villas, towers and factories. Send your size and quantity to our Deira, Dubai counter for a quick price.
