GF+ Aquasystem PP-R Tee
GF+ Aquasystem PP-R Tee — An equal tee that takes a 90° branch of the same diameter off the line. All three ends are for socket fusion welding; it is used at distribution points to split a line in two or to join two lines.
Applications
- Bathroom and kitchen branches in in-apartment distribution
- Floor outlets from risers
- Flow and return splits in heating lines
Key features
- Three equal ends, Ø20 – Ø160 mm
- PN25 pressure rating
- Gasket-free, leak-tight joint by socket fusion welding

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 used if the branch has a different diameter?
For outlets of different diameters, a PP-R Reducing Tee is used.
Which jointing method is used for Ø160 mm?
For Ø160 mm, GF offers two options: butt welded (SDR11) and socket welded. This product is socket welded and can be welded to pipes of all SDR series.
