Pressure test plugs provide a temporary way to seal compatible pipework or outlets while an installation is being tested, commissioned or protected during ongoing building work. They are useful for checking system integrity before final appliances, fittings or terminal connections are installed.
The plug must be suitable for the relevant pipe or fitting system and used within its specified pressure and temperature limits. Installers should confirm that the pipe end or connection is clean, undamaged and prepared correctly before fitting the test plug.
Pressure testing should always follow the system manufacturer’s guidance and the applicable project procedure. Test pressure, duration and medium must be appropriate for the installation, and plugs should remain accessible throughout the test.
Explore the available pressure test plugs below, together with related adapters and preparation tools, to support safe and orderly plumbing and heating installation work. You may also find the related pipe adapters and ancillaries and pipe cutters useful when completing the system.
