Copper reducing tee SANHA 5130 28 x 15 x 28 mm, model 15130281528

SANHA copper reducing tee 5130 28 x 15 x 28 mm is a three-way plumbing fitting designed to create a reduced branch in copper piping systems. Manufactured from copper, the fitting provides a secure transition between two larger 28 mm pipes and a smaller 15 mm branch, enabling reliable flow distribution for potable water and heating installations in residential and light commercial environments.

Advantages

The copper construction offers corrosion resistance and durable mechanical performance in typical plumbing conditions. The precise dimensional tolerances ensure close fit and compatibility with standard copper joining methods used in plumbing, supporting leak‑tight joints when installed correctly. Its reducing design simplifies system layouts by providing a compact and direct branch connection without additional adapters.

Suitable for

• Domestic potable water distribution systems
• Residential and small commercial heating circuits
• Pipe size transitions where a 28 mm main run feeds a 15 mm branch
• Plumbing repairs and system modifications requiring a reduced tee

Key specifications

• Material: copper
• Configuration: reducing tee, branch off main run
• Connection sizes: two ends 28 mm, branch 15 mm
• Application: potable water and heating systems
• Suitable joining methods: standard copper soldering or compatible mechanical joining techniques

How to use

Prepare pipe ends by cutting square and cleaning the surfaces to remove oxidation and contaminants. Fit the reducing tee onto the prepared pipes, ensuring correct orientation of the 28 mm runs and the 15 mm branch. Join according to the chosen copper joining method—typically soldering (brazing) or a compatible mechanical connection—following manufacturers' procedures for flux, heat, and cooling to achieve a secure, leak‑tight joint. After installation, pressure test the system per local codes to verify integrity.

Usage recommendations

Use appropriate safety equipment and follow local plumbing standards during installation. Select a joining technique suitable for the piping system and operating conditions; for potable water systems, use approved materials and procedures to maintain water quality. Inspect joints visually and perform pressure testing after installation to confirm leak‑free performance.
