GF+ Aquasystem PP-R Socket (Coupler)
GF+ Aquasystem PP-R Socket (Coupler) — A fitting that joins two pipes of the same diameter end to end in a straight line. It is used to extend pipe length and to cut out a damaged pipe section and insert a new one.
Applications
- Extending pipe lengths (Aquasystem pipes come in 4 m lengths)
- Replacing the damaged section during repairs
- Risers and main distribution lines
Key features
- Both ends for socket fusion welding
- Ø20 – Ø160 mm, PN25 pressure rating
- Short body, minimal space on the line

Socket fusion welding times

|---|---|---|---|---|

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 are different diameters joined on the same line?
For different diameters, a PP-R Reducer is used instead of a socket.
