SANHA press reducing coupling 18 x 15 mm, model 162431815

The SANHA press reducing coupling 18 x 15 mm, model 162431815 is a compact press-fit reducer designed to join copper or press-compatible pipes of different diameters in potable water and heating systems. The fitting provides a secure transition from an 18 mm supply line to a 15 mm branch, enabling reliable, low-profile connections where space is limited. It is intended for use with press-connection tools and corresponding press jaws matched to the fitting profile.

Advantages

The press reducing coupling offers a leak-resistant mechanical joint achieved by a press tool, eliminating the need for soldering or threaded connections. Its compact design reduces space requirements and simplifies installation in confined areas. The reducer is suitable for use in systems with potable water and heating media, providing consistent flow adaptation between different pipe sizes while maintaining system integrity when installed according to manufacturer's press procedures.

Suitable for

• Connecting 18 mm main lines to 15 mm branch lines in domestic potable water systems
• Reducing pipe diameter in central heating and radiator supply circuits
• Installations where press-fit connections are required to speed up assembly and reduce fire risk
• Retrofitting or extending existing press-fit piping networks with differing pipe sizes

Key specifications

• Nominal dimensions: 18 mm x 15 mm
• Connection type: press-fit reducer compatible with press-connection tooling
• Application media: potable water and heating systems
• Design: compact, low-profile reducer for tight installation spaces

How to use

Ensure pipes are cut squarely, deburred and cleaned before assembly. Slide the SANHA press reducing coupling onto the prepared pipe ends so that the pipe reaches the correct insertion depth. Use an appropriate press tool and matching pressing jaws for the fitting profile and pipe material. Perform the press operation following the press tool manufacturer's instructions and applicable installation standards. Verify each pressed joint visually and, where required, perform pressure testing of the system according to local regulations.

Usage recommendations

Use only press tools and jaws recommended for SANHA press fittings and ensure compatibility with the pipe material. Follow relevant national and local codes for potable water and heating installations, and observe manufacturer guidance on maximum operating pressures and temperatures for press systems.
