Press-fit tee fitting SiGMA-Li MT251616 25x16x16 mm copper-replacement red

Press-fit tee fitting SiGMA-Li MT251616 25x16x16 mm copper-replacement red is a press-connection branch fitting designed for plumbing and heating installations. It connects a 25 mm supply run to two 16 mm outlets, providing a compact solution for creating a branch with a consistent press joint. The red finish supports visual identification of the circuit or medium and the fitting is intended for use with compatible press tools and press-suitable pipes in potable water, heating and sanitary systems.

Advantages

The fitting provides a secure press joint that eliminates the need for soldering, reducing installation time and the requirement for open flame. Its compact geometry facilitates installation in confined spaces and simplifies routing of branching lines. The red coating aids in system organisation and identification during installation and maintenance. The design is compatible with standard press tools and press jaws intended for similar copper-replacement fittings.

Suitable for

• Creating a branch from a 25 mm main line to two 16 mm distribution lines
• Potable water installations where press fittings are specified
• Heating and radiator connections in residential and light commercial systems
• Sanitary plumbing where a compact, non-soldered branch is required

Key specifications

• Type: Press-fit tee (branch fitting)
• Material: copper-replacement metal suitable for press connections
• Dimensions: 25 x 16 x 16 mm (main run x outlet x outlet)
• Finish: red coating for system identification
• Connection method: press connection compatible with press tools and jaws designed for similar fittings
• Application media: potable water, heating, sanitary systems

How to use

Prepare the pipe ends by cutting square and deburring to the required depth, ensuring the pipe is clean and free of damage. Insert the pipes fully into the fitting until they reach the internal stop. Position the appropriate press jaw around the fitting's press sleeve and perform the press operation according to the press tool manufacturer's instructions. Verify each pressed joint visually and, where applicable, with a test gauge or marking method specified for the system. After pressing, complete system testing (pressure test) following applicable standards and local codes.

Usage recommendations

Use press jaws and tools that are approved for copper-replacement press fittings and sized for 25 mm and 16 mm connections. Store fittings in a dry place and protect from mechanical damage prior to installation. Follow local regulations and manufacturer guidance for pressure testing and system commissioning to ensure long-term reliability.
