SANHA reducing tee SANHA-Therm 3xZW 28x15x28 for pipe systems

SANHA reducing tee SANHA-Therm 3xZW 28x15x28 is a precision-formed plumbing fitting designed to create a branch connection between pipes of two different diameters. Made for use in plumbing and heating systems, the fitting has two 28 mm outlets and a reduced 15 mm branch to accommodate transitions between larger distribution lines and smaller supply runs. Constructed for compatibility with copper and copper-alloy tubing, this reducing tee supports distribution, repair and retrofit installations where a reliable, space-efficient branch is required.

Advantages

The SANHA-Therm reducing tee delivers a consistent internal profile and dimensional accuracy to ensure secure joints and predictable fluid flow. Its design minimizes turbulence at the diameter transition and facilitates straightforward installation with standard joining methods suitable for copper systems. The compact form factor allows use in confined spaces while maintaining stable connections at both the main line and the reduced branch.

Suitable for

• Domestic and commercial hot and cold water distribution
• Heating circuit branch connections and radiators
• Repair, retrofit and extension of existing copper pipe networks
• Integration into copper-alloy plumbing in residential and light-commercial buildings

Key specifications

• Configuration: reducing tee with two equal large outlets and one reduced branch
• Outlet diameters: main line 28 mm (two ports), branch 15 mm
• Material compatibility: copper and copper-alloy tubing
• Application: plumbing and heating systems for distribution, repair and retrofit
• Connection type: designed for standard joining methods used with copper tube systems

How to use

Prepare the pipes by cutting square and deburring the tube ends, then clean to remove any oxidation or contaminants. Fit the reducing tee to the prepared pipes ensuring full insertion of each tube into the respective port. Complete joints using the appropriate joining method for copper systems (such as soldering, brazing, or approved mechanical connections) following relevant national codes and manufacturer recommendations. Verify alignment and support the assembly to avoid stress on the connections.

Usage recommendations

Use the SANHA-Therm reducing tee in systems with compatible copper tubing and select the joining technique that matches system pressure and temperature requirements. Ensure proper pipe support and thermal expansion allowances. Observe applicable standards and local plumbing regulations when installing in potable water or heating systems.
