Galvanized Sockets
A galvanized socket is a zinc-coated cast fitting with two female-threaded ends that joins two galvanized steel pipes of the same size in a straight line. It keeps the coating continuous at the pipe joint.
Sockets have the widest size range in the galvanized family: 13 sizes from 1/4″ to 6″. They are used to join pipes in water distribution, sprinkler, irrigation and large-bore fire lines.
Main Applications
- Joining galvanized water pipes
- Large-bore fire and sprinkler mains (5″ – 6″)
- Extensions in irrigation lines
- Creating a female-threaded port at a pipe end
- Intermediate joints at tank and booster set connections
- Line repairs after maintenance

Which material? Using a galvanized socket on galvanized pipe keeps the zinc protection unbroken at the joint; black sockets are preferred on black pipe.

How to Choose?
- Measure the pipe sizeBoth pipes must be the same size; if not, use a reducing socket.
- Assess dismantling needsIf the joint will be opened later, prefer a taper seat union.
- Choose the surface for the mediumUse galvanized sockets on galvanized pipe and black sockets on black pipe.
- Confirm the large sizeAsk for the pressure rating of 5″ and 6″ sockets before ordering.
