GF+ Aquasystem PP-R Union
GF+ Aquasystem PP-R Union — An all-plastic union with both ends for welding that creates a connection point which can be taken apart and reassembled without cutting the line. It is used upstream and downstream of equipment that needs maintenance, such as pumps, meters and filters.
Applications
- Pump, filter and water meter connections
- Line sections that must be removed for maintenance
- Manifold and boiler room connections
Key features
- Detachable connection without cutting the line
- Both ends for socket fusion welding
- Per GF data, for PN10 hot and cold water applications

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
What is the pressure rating?
According to the GF data sheet, the PP-R union is for PN10 hot and cold water applications; at higher pressure points, prefer the metal threaded transition unions.
