GF+ Aquasystem PP-R Male Threaded Adapter (Round)
GF+ Aquasystem PP-R Male Threaded Adapter (Round) — A transition fitting with one end welded to the pipe and a nickel-plated brass male thread on the other. It connects the PP-R line to threaded equipment such as valves, meters, combi boilers and filters.
Applications
- Combi boiler, water heater and storage tank connections
- Valve, water meter and filter inlets
- Transition to threaded manifolds and fixtures
Key features
- Nickel-plated brass male thread (BSPP-G)
- Round body
- 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 |
| Ø32 | 16.5 | 8 | 6 | 4 |
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 the thread sealed?
Hemp or sealing tape is wrapped around the thread. When tightening the brass part, hold it with a wrench on the metal part, not on the PP-R body.
