GF+ Aquasystem PP-R Threaded Plug
GF+ Aquasystem PP-R Threaded Plug — A threaded plug that temporarily closes threaded outlets (for example faucet connections). It keeps the outlet closed during plastering and pressure testing until the fixture is installed.
Applications
- Closing faucet and fixture outlets during pressure testing
- Protecting outlets during plastering and tiling
- Spare outlets for future use
Key features
- Threaded design: easy to fit, easy to remove
- Long body: stays outside the plaster surface and is not lost
- Ø20 and Ø25 mm

Socket fusion welding times
| Pipe diameter | Welding depth (mm) | Heating (s) | Joining time (s) | Cooling (min) |
|---|---|---|---|---|
| Ø20 | 14 | 5 | 4 | 2 |
| Ø25 | 15 | 7 | 4 | 2 |
Values per DVS 2207-11 at +20 °C ambient and 260 °C heating tool temperature. Below +5 °C, extend the heating time by about 50%. Heating time starts when pipe and fitting are fully seated on the heating dies; during the joining time the parts may be aligned axially without twisting.
Installation tips
- Cut the pipe square with a pipe cutter and mark the welding depth on the pipe.
- Push pipe and fitting onto the heating dies at the same time without twisting; when the heating time is over, join them quickly and axially.
- Do not twist the parts after the joining time; do not pressurize the line before the cooling time has passed.
- Pressure-test the installation before closing walls or screed.
Frequently asked questions
Is it used for permanent closure?
The threaded plug is for temporary use. To close a line permanently, a welded PP-R End Cap is used.
