SANHA copper reducing tee 18 x 18 x 15 mm model 5130

SANHA copper reducing tee 18 x 18 x 15 mm model 5130 is a three-way copper fitting designed to join two equal-diameter runs with a reduced branch. Manufactured from copper for compatibility with copper piping systems, this reducing tee provides a stable mechanical and hydraulic connection where a change in diameter from 18 mm to 15 mm is required. It is suitable for potable water, heating and refrigeration applications and is intended for use in plumbing and HVAC assemblies that use soldered or press-joined copper connections.

Advantages

The reducing tee offers precise dimensional conformity for consistent fit with standard 18 mm and 15 mm copper tubes. Copper construction ensures good corrosion resistance and thermal conductivity for heating and refrigeration circuits. The model's branch reduction simplifies transitions between pipe sizes without additional adapters, reducing potential leak points and installation complexity.

Suitable for

• Domestic and commercial potable water distribution
• Central heating pipework and radiator connections
• Refrigeration and chilled-water circuits
• Plumbing installations requiring a reduction from 18 mm to 15 mm

Key specifications

• Material: copper
• Configuration: reducing tee (two equal inlets, one reduced branch)
• Connection diameters: 18 mm, 18 mm, 15 mm
• Application: potable water, heating, refrigeration systems
• Compatibility: designed for use with standard copper tubing and common joining methods (soldering/press systems)

How to use

Select the reducing tee where a branch requires a smaller diameter connection and ensure tubing ends are clean, deburred and cut square. Fit the 18 mm runs and the 15 mm branch according to the chosen joining method (soldering, brazing or compatible press fitting), following the pipework layout and local regulations. After joining, pressurize and inspect the assembly for leaks and verify hydraulic performance before returning the system to service.

Usage recommendations

Use appropriate flux and cleaning procedures for soldered joints, or the correct tooling and press profiles for press-join systems. Verify material compatibility with system fluids and follow applicable installation standards for potable water and heating setups.
