Press-fit tee SiGMA-Li MT251625, copper‑plated red, 25×16×25 mm

The Press-fit tee SiGMA-Li MT251625, copper-plated red, 25×16×25 mm is a press fitting designed to form a compact T-connection between three pipes in plumbing and heating installations. Manufactured for solder-free joining, the fitting enables reliable mechanical connections when used with compatible press tools and jaws. Its copper-plated red finish is intended for visible identification and corrosion resistance where appropriate for the installation environment.

Advantages

This press-fit tee provides a secure, solder-free connection that reduces the need for open flame work and speeds up installation times. The press joint ensures consistent mechanical performance when installed with the correct pressing equipment. The compact T-shape allows efficient branching of supply or return lines in confined spaces, and the copper-plated surface supports compatibility with metallic pipe systems and offers an additional layer against local corrosion.

Suitable for

• Potable water distribution systems where press fittings are specified
• Residential and commercial heating circuits
• Branching supply lines in confined or concealed spaces
• Installations requiring solder-free, mechanical pressing joints

Key specifications

• Configuration: T-shaped press fitting for three-pipe connection
• Connection method: press-fit (mechanical pressing with compatible tools)
• Material finish: copper-plated red surface
• Pipe diameters: 25 mm × 16 mm × 25 mm
• Application: potable water and heating systems where press joints are permitted

How to use

Select the correct pressing tool and jaw size compatible with the 25 mm and 16 mm ends of the fitting. Prepare pipe ends by deburring and ensuring correct insertion depth according to the pipe and pressing system requirements. Insert pipes fully into the fitting until they reach the stop, then perform the pressing operation with the appropriate press tool to create the mechanical joint. Verify each pressed connection visually and, where applicable, perform pressure tests in accordance with local regulations and project specifications.

Usage recommendations

Use only press tools, jaws and seals that are declared compatible by the press system manufacturer and follow system-specific instructions. Avoid using the fitting in systems with media or temperatures outside the stated limits of the press fitting system. Store fittings in a dry environment to prevent surface contamination prior to installation, and inspect each fitting for damage before use.
