Copper Reducing Tee SANHA 5130 42 x 28 x 42 mm

Copper reducing tee SANHA 5130 42 x 28 x 42 mm is a plumbing and heating fitting designed to join three copper pipes where the branch connection has a smaller diameter than the main run. The fitting is compatible with press-fit or soldering installation methods and is intended for use in potable water and heating systems. Its geometry provides a reliable transition from a 42 mm main line to a 28 mm branch line while maintaining flow continuity and mechanical stability.

Advantages

The reducing tee offers a compact, robust connection that simplifies the creation of a branch from a larger main pipeline to a smaller secondary line. Constructed in copper, the fitting provides corrosion resistance and thermal conductivity appropriate for hot-water and heating applications. The design supports both press-fit and soldered joints, allowing flexibility for different installation practices and tools. Its standardized dimensions ensure compatibility with common copper tube sizes in commercial and residential systems.

Suitable for

• Distribution of potable water in residential and commercial buildings
• Branching in central heating and hot-water circulation systems
• Hydronic systems and radiators requiring a reduction from 42 mm to 28 mm
• Plumbing repairs or retrofits where a reduced branch connection is needed

Key specifications

• Material: copper
• Connection types: press-fit or solderable joints
• Main line diameter: 42 mm
• Branch diameter: 28 mm
• Configuration: reducing tee (two in-line ends and one reduced branch)

How to use

Select the appropriate installation method for the project—press-fit or soldering—according to the system requirements and local codes. Prepare copper tube ends by cutting square, deburring, and cleaning the surfaces. For press-fit assembly, follow the press-tool manufacturer’s instructions, ensuring proper insertion depth and full engagement before pressing. For soldered joints, apply suitable flux and solder, heat uniformly to achieve a clean capillary fill, and allow the joint to cool undisturbed. After installation, pressure-test the system according to applicable standards to verify leak-free performance.

Usage recommendations

Confirm compatibility of the fitting with the pipe wall thickness and the chosen joining method. Use appropriate personal protective equipment and follow local plumbing codes. When switching between press-fit and soldering methods, ensure the fitting surface condition and any seals or O-rings (if present in specific variants) are suitable for the selected method.
