Pressure test plug for 20 mm pipes blue
Description
Pressure Test Plug Blue 20 mm – Reusable
The blue pressure test plug 20 mm is an essential tool for every plumbing and heating installation company. Its reusable design saves both time and money compared to single-use press fittings.

The plug is designed to cap multilayer pipes PEX/AL/PEX and PERT/AL/PERT with a dimension of 20 x 2.0 mm during pressure testing of water and heating installations. The robust threaded body with an o-ring seal ensures a reliable seal even at high pressures.
Where can the plug be used?
- Pressure testing – an alternative to single-use press fittings in incomplete installations
- Underfloor heating – testing prior to pouring the concrete screed
- Pipe protection – sealing pipes against contamination at wall penetrations
- Winter conditions – pressure testing with compressed air at sub-zero temperatures


Easy installation – the plug can be fitted using a flat spanner, hex key, or a drill driver with a hex bit. The ergonomic shape provides a secure grip for quick insertion and removal from the pipe.
