## Summary description

SANHA Therm reducing tee 3xZW 28×18×28 is a pipe fitting designed for heating and plumbing systems to connect pipes of diameters 28 mm and 18 mm. The reducing tee (3xZW) provides a reduced branch for flow diversion or connection of smaller-diameter lines. Suitable for use in central heating, radiator connections and hot water circuits where reliable, size-changing branches are required.

## Long description

SANHA Therm reducing tee 3xZW 28×18×28 is a metal pipe fitting engineered for heating and plumbing systems that require a change in pipe diameter. The fitting provides a reduced branch from a 28 mm main run to an 18 mm branch and back to 28 mm, enabling reliable diversion or connection of a smaller line within central heating, radiator connections and hot water circuits. The design supports steady flow and pressure conditions typical for residential and light-commercial heating installations.
Advantages
The reducing tee is manufactured to ensure dimensional accuracy and a consistent seal at each connection point, reducing the risk of leaks when installed correctly. Its construction allows compatibility with common installation methods used in heating systems and simplifies transitions between pipe sizes without the need for additional adapters. The compact shape conserves space in manifolds and installation cavities while providing a durable mechanical junction for temperature and pressure loads found in hot water circuits.
Suitable for
Branching off a smaller-diameter heating circuit from a 28 mm supply line
Connecting thermostatic radiator valves or distribution lines in central heating systems
Hot water circulation loops requiring a reduced-diameter feed
Retrofit work where a size change is needed without replacing existing mains
Key specifications
Main run outside diameter: 28 mm
Branch outside diameter: 18 mm
Type: reducing tee with reduced branch (3xZW)
Intended application: heating and hot water plumbing systems
Material: metal compatible with typical heating system media
Connection form: press-fit or fusion-compatible depending on SANHA Therm system requirements
How to use
Select the reducing tee matching the pipe material and diameter of the existing installation. Prepare pipe ends by cutting square and deburring, then follow the SANHA Therm system instructions for the appropriate joining method. Insert pipes fully into each port and complete the joint using the specified press or fusion tool to achieve a secure, leak-tight connection. Verify alignment and support the assembly to avoid stress on the joints. After installation, perform a pressure test of the heating circuit in accordance with local regulations to confirm sealing integrity.
Usage recommendations
Ensure compatibility with the specific SANHA Therm installation system and use recommended jointing tools and seals. Observe system pressure and temperature limits and provide adequate mechanical support for the change in pipe size to prevent strain on the fitting and connected lines.
