Pressure test plugs – sealing pipes for pressure testing
Pressure test plugs seal the ends of pipes and fittings during pressure tests with water or compressed air. This category contains 12 products with G 1/2" and G 3/4" threads and for 16–32 mm pipes, in blue and red. They are designed for installers and companies working on water, heating and underfloor heating systems.
What you’ll find in this category
- Plugs with G 1/2" and G 3/4" threads and an O-ring seal, each available in blue and red.
- Plugs for 16 mm and 20 mm pipes, in blue and red. The 16 mm version is specified for 16 x 2.0 mm pipes.
- Plugs for 25/26 mm and 32 mm pipes, in blue and red.
How to choose
- Thread or pipe diameter: choose G 1/2" or G 3/4" for threaded connections. For pipe ends, select a 16, 20, 25/26 or 32 mm plug.
- Pipe type: the 16 mm plug is designed for 16 x 2.0 mm PEX/AL/PEX and PERT/AL/PERT multilayer pipes.
- Colour: blue identifies cold water points and red identifies hot water points. This makes connections easier to identify on site.
- Installation method: the 16 mm plug can be installed using an open-ended spanner, an Allen key or a power screwdriver with a hex bit.
Typical applications
These plugs are suitable for leak testing incomplete water and central heating systems as an alternative to single-use press fittings. They are used to test underfloor heating systems before the screed is poured. They also protect pipes from contamination at wall penetrations. At sub-zero temperatures, they allow testing with compressed air.
Frequently asked questions
Can the test be carried out with compressed air?
Yes. The plugs are designed for pressure testing with water or compressed air. The product descriptions also state that compressed air can be used for testing at sub-zero temperatures.
Can the plugs be reused?
The plugs for 16 mm pipes are described as reusable. They replace single-use press fittings when testing incomplete systems. The thread and O-ring seal provide a watertight seal.
What do the plug colours indicate?
Blue identifies cold water points and red identifies hot water points. This makes connections easier to identify during construction.
