GF+ Aquasystem PP-R Reducing Tee
GF+ Aquasystem PP-R Reducing Tee — A reducing tee used to take branches of smaller or different diameters off the main line. Because it combines a tee and a reducer in one piece, it reduces the number of welds and the installed length.
Applications
- Taking a smaller floor branch off a riser
- Reduced outlets on manifolds and distribution lines
- Taking a branch while the main line reduces at one end (types with three different ends)
Key features
- 30 sizes from 25-20-20 up to 110-75-110 mm
- Two types: main line continuing at the same diameter (A-B-A) and all three ends different (Type 2)
- PN25 pressure rating

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 the size read?
The order is main line inlet – branch – main line outlet. 32-20-32: main line Ø32, branch Ø20 mm. With three different sizes such as 32-20-25, the main line also narrows at the outlet.
