Compression Tee fitting SiGMA-Li MT252516 – red, 25×25×16 mm

The SiGMA-Li MT252516 compression tee fitting in red is a press-style connector designed to create a branch between two 25 mm pipes and a single 16 mm pipe. Manufactured for use in potable water and heating systems, the fitting provides a compact, color-coded solution for plumbers and installers who need a durable, leak-resistant press connection for mixed-diameter piping. Its red finish helps with quick identification on-site and supports standardized installation workflows.

Advantages

The compression tee offers a reliable press-fit connection that reduces assembly time compared with traditional soldering or threaded joints. Its design supports tight seals and consistent mechanical strength across repeated installations, minimizing the risk of leaks. The compact dimensions allow installation in confined spaces and the color coding simplifies system layout and maintenance. Materials and construction are selected to meet the demands of potable water and heating applications.

Suitable for

• Branching potable water supply lines where two 25 mm runs connect to a 16 mm branch
• Heating circuit branches in residential and light commercial systems
• Retrofit or new-build installations requiring press-fit connections for copper or compatible piping
• Situations where rapid, consistent, and leak-resistant joins are required by professional plumbers

Key specifications

• Connection type: compression/press-style tee for mixed diameters
• Primary outlet diameters: 25 mm and branch diameter: 16 mm
• Material: corrosion-resistant metals and components suitable for water and heating systems
• Finish: red color for identification
• Installation orientation: suitable for horizontal or vertical branches within piping runs

How to use

Prepare the pipes by cutting square and deburring the ends to ensure full insertion of the tubes into the fitting. Slide or position the fitting onto the 25 mm main lines and insert the 16 mm branch pipe fully to the stop. Use the appropriate press tool and jaw for the specified diameters to compress the fitting according to the tool manufacturer’s instructions. After pressing, verify the mechanical integrity of each joint and perform a pressure test of the system to confirm leak-free installation.

Usage recommendations

Follow local plumbing codes and the press tool manufacturer’s guidelines for jaw selection and pressing parameters. Ensure pipes are compatible with compression/press fittings and free from contamination or deformation before assembly. Perform a pressure test after installation and inspect color-coded fittings periodically during maintenance.
