Reducing tee PP‑R pipe fitting KAN‑therm 25/25/20

Reducing tee PP‑R pipe fitting KAN‑therm 25/25/20 is a polypropylene random copolymer (PP‑R) branch fitting designed to connect and reduce between 25 mm and 20 mm lines. It is intended for use in pressure piping systems for hot and cold water and heating circuits, providing a compact transition with smooth internal flow. The fitting is supplied by KAN‑therm and matches standard PP‑R installation practices for residential and light commercial plumbing and heating distribution.

Advantages

This reducing tee offers corrosion‑free construction and chemical resistance inherent to PP‑R material, ensuring long service life in potable water and heating systems. Its socket ends allow for solvent-free, heat fusion installation which creates a homogeneous joint with the pipe, reducing leak risk when installed correctly. The compact design facilitates installation in confined spaces and simplifies transitions between different pipe diameters without additional adapters.

Suitable for

• Domestic hot and cold water distribution
• Heating circuits and radiator branches
• Plumbing installations in apartments and single‑family houses
• Light commercial sanitary and distribution systems

Key specifications

• Material: polypropylene random copolymer (PP‑R)
• Connection type: socket for fusion welding
• Branch dimensions: main runs 25 mm, reduced outlet 20 mm
• Application: pressure potable water and heating systems
• Temperature range suitable for hot and cold water installations (per PP‑R material limits)

How to use

Prepare pipes by cutting squarely and deburring ends before insertion. Clean the socket and pipe ends to remove dirt and grease. Use a compatible PP‑R fusion tool (socket fusion or butt fusion as appropriate) and follow the tool manufacturer’s temperature and time settings to create a uniform welded joint. After cooling, inspect joints for correct alignment and perform pressure testing of the system according to local codes and project requirements.

Usage recommendations

Select fusion parameters and cooling times that match pipe wall thickness and local standards. Store fittings away from direct sunlight and prolonged heat exposure prior to installation. Use appropriate supports and thermal expansion allowances in heating circuits to prevent mechanical stress on joints.
