Pressure test plug 3/4" blue

The plug is designed for blanking off pipes and fittings during pressure tests carried out using water or compressed air. The blue colour allows cold water connection points to be intuitively marked throughout the installation, making it easier to identify outlets at the construction stage.

The G 3/4" thread with an o-ring seal ensures a secure connection — once tightened, the plug maintains a leak-free seal at pressures exceeding those used in standard pressure tests. This means it replaces single-use press-fit connectors that generate unnecessary costs when testing incomplete installations.

Where does it excel?

• Pressure testing of water and central heating systems – blanking open pipe ends prior to pressure testing
• Underfloor heating installations – securing circuits before concrete screed is poured
• Wall penetrations – protecting pipes from construction debris during finishing works
• Testing in sub-zero temperatures – enables pressure tests using compressed air in winter conditions
• Point identification – the blue colour makes it easy to identify cold water connections
