SANHA reducing tee SANHA-Therm 3xZW 28x22x28 copper press fitting

The SANHA reducing tee SANHA-Therm 3xZW 28x22x28 copper press fitting is designed to connect a 28 mm main line to a reduced 22 mm branch in heating and plumbing installations. Manufactured from copper and equipped with press (ZW) connections on all three ends, this fitting provides a compact solution for splitting a pipeline while maintaining a sealed, durable joint when installed with compatible press tools.

Advantages

This copper reducing tee offers corrosion-resistant properties and good thermal conductivity suitable for hot water and heating systems. Press connections ensure fast, consistent joint formation and reduce the risk of leakage compared with traditional soldered or threaded joints when assembled with the appropriate press tool and seals. The reduced middle branch enables reliable transitions between different pipe diameters while maintaining compact dimensions for space-constrained installations.

Suitable for

• Domestic and commercial central heating distribution
• Hot and cold water plumbing systems
• Repair and retrofit projects requiring a reduction from 28 mm to 22 mm
• Professional installations using press-fitting tools

Key specifications

• Material: Copper
• Connection type: Press fitting (ZW) on all three ends
• Dimensions: 28 mm x 22 mm x 28 mm (main-branch-main)
• Application: Heating and potable water systems
• Joint type: Press-sealed joints when used with compatible press tool and insert

How to use

Prepare pipe ends by cutting square and deburring the inner and outer edges. Slide the compatible press-fit sleeve or ring into position and insert the pipe fully into each fitting end until it seats. Use a suitable press tool and the correct jaw size for 28 mm and 22 mm connections to form the press joints. Verify each pressed joint visually and, if required by local codes, perform a pressure test to confirm leak-tightness before commissioning the system.

Usage recommendations

Use only manufacturer-recommended O‑rings or seals and press-tool jaws sized for 28 mm and 22 mm to ensure reliable joints. Store fittings in a dry environment and avoid mechanical damage before installation. Follow applicable local standards and regulations for potable water and heating system installations, and if in doubt consult a certified installer.
