Reducer Tee KAN-therm TR2516 — polypropylene (PP-R) pipe fitting 25 mm to 16 mm

KAN-therm TR2516 is a polypropylene (PP-R) reducer tee designed to connect a 25 mm main run with a 16 mm branch in hot and cold water installations and heating systems. The fitting provides a smooth transition between pipe diameters while maintaining the chemical and thermal resistance characteristics of PP-R material. It is intended for systems that use heat-fused joints to ensure leak-free, long-lasting connections.

Advantages

The reducer tee offers uniform wall thickness and consistent material quality to support reliable heat fusion and a tight seal. Its corrosion- and scale-resistant polypropylene composition reduces maintenance needs compared with metal fittings and preserves water quality. The compact design facilitates installation in confined spaces and allows straightforward integration into existing PP-R networks without additional adapters when connecting 25 mm mains to 16 mm branches.

Suitable for

• Domestic and commercial hot water distribution
• Cold water supply lines
• Low-temperature heating circuits and underfloor heating manifolds
• Plumbing systems using PP-R pipes and fittings

Key specifications

• Material: polypropylene random copolymer (PP-R)
• Main run diameter: 25 mm
• Branch diameter: 16 mm
• Connection type: socket for heat fusion welding
• Suitable for use with potable water and heating media within PP-R system limits
• Compact T-shaped design for space-efficient installation

How to use

Prepare pipe ends by cutting squarely and removing burrs and dirt. Ensure pipes and fitting sockets are clean and dry. Use an appropriate PP-R fusion tool set to the correct temperature and follow the tool manufacturer's parameters for socket fusion of 25 mm and 16 mm connections. Insert pipes to the required depth, hold until the joint cools to form a permanent welded connection, and avoid movement during cooling. Verify alignment and test the assembled system according to applicable pressure and temperature testing procedures.

Usage recommendations

Store fittings in a clean, dry place away from direct sunlight. During installation, follow local codes and PP-R system guidelines for maximum operating temperature and pressure. For best long-term performance, use compatible PP-R pipes and fusion equipment and allow sufficient cooling time after fusion before pressure testing or placing the system into service.
