GF+ Aquasystem PP-R Socket with Union Nut
GF+ Aquasystem PP-R Socket with Union Nut — A transition fitting consisting of a PP-R body welded to the pipe and a freely rotating brass nut (female thread). It connects to the male-threaded ends of faucets and fixtures without rotating the line or the fixture.
Applications
- Faucet, trap and fixture connections
- Detachable connection of male-threaded equipment
- Meter and valve connections
Key features
- Freely rotating nut: connects without rotating
- Nickel-plated brass female thread (BSPP-G)
- PN25 pressure rating

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.
- When tightening a threaded joint, hold the brass part with a wrench; do not apply torque to the PP-R body. Use hemp or sealing tape on the thread.
- Pressure-test the installation before closing walls or screed.
Frequently asked questions
How is sealing achieved?
In the nut connection, sealing is provided by a gasket; there is no need to wrap hemp around the thread.
