## Long description

Press-fit tee fitting SiGMA-Li MT251616 25x16x16 mm copper-replacement red is a press-connection branch fitting designed for plumbing and heating installations.

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

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.

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.

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.
