What Is the GI Hollow Plug Used For?
Water systems are rarely built with every outlet in use from day one. This plug screws into a ½" female-threaded opening — the branch of a tee, the end of a socket or elbow, or a spare port — to seal it until a tap, branch line or gauge is added later. It is also handy for closing openings temporarily while a new section of pipework is pressure tested.
When fitting it, clean the female threads, apply sealing tape or compound to the plug's male thread and tighten firmly without forcing. Recording where plugs have been fitted helps maintenance teams find future connection points quickly, and removing a plug is straightforward when the line needs extending.
What to Specify When Ordering
- Number of ½" plugs for spare or future outlets.
- Whether you also need caps for closing male-threaded pipe ends.
- The thread standard on your site, so compatibility can be checked.
