GF+ Aquasystem PP-R Crossover
GF+ Aquasystem PP-R Crossover — A crossover fitting that carries a pipe line over another pipe crossing it at a right angle. After the crossover, the line continues on the same axis.
Applications
- Points where hot and cold water lines intersect
- Crossing heating flow and return lines
- Preventing pipes from stacking on top of each other in the screed
Key features
- Wide-radius crossing, low flow resistance
- Joined by socket fusion welding
- 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.
- Pressure-test the installation before closing walls or screed.
Frequently asked questions
How is a crossover positioned?
The arched part of the crossover is positioned to pass over (or under) the opposing pipe; the line continues on the same axis.
