Reduced tee fitting SiGMA-Li TR2516, polypropylene (PP), 25×16×25 mm

SiGMA-Li TR2516 is a reduced tee fitting made of polypropylene (PP) with dimensions 25×16×25 mm. It is designed to connect two 25 mm pipe runs with a single 16 mm branch, providing a compact junction for water distribution and low-pressure plumbing. The polypropylene construction ensures resistance to corrosion and chemical degradation while keeping the fitting lightweight for easier handling and alignment during installation. This fitting is compatible with common joining methods for PP pipes when the correct connection technique and seals are used.

Advantages

The SiGMA-Li TR2516 offers a straightforward geometry that simplifies creating branches in piping systems without adding significant bulk. Polypropylene material provides chemical and corrosion resistance, making the fitting suitable for potable water, irrigation, and many low-pressure fluid applications. Its reduced tee design allows transition between pipe diameters while maintaining a compact footprint. The lightweight plastic construction reduces strain on supporting structures and facilitates faster manual installation compared with heavier metallic fittings.

Suitable for

• Domestic and commercial water supply networks with low pressure
• Irrigation systems for gardens and small agricultural plots
• Distribution branches in plumbing for sinks, outdoor taps, and auxiliary lines

Key specifications

• Material: polypropylene (PP)
• Configuration: reduced tee (two equal ends and one smaller branch)
• Dimensions: main ends 25 mm, branch 16 mm
• Application pressure range: suitable for low-pressure systems (follow system design limits)
• Resistance properties: corrosion-resistant and chemically stable in typical water service
• Weight: lightweight plastic construction for easier handling

How to use

Prepare the mating pipe ends by cutting squarely and removing burrs or debris. Confirm compatibility between the SiGMA-Li TR2516 fitting and the chosen pipe type and joining method (for example, solvent welding or mechanical compression for compatible PP systems). Assemble according to the pipe manufacturer’s recommended procedures, ensuring correct insertion depth and alignment. Apply seals or adhesive if required by the chosen joining method, and allow any cure time specified before pressurizing the system. After installation, inspect joints for secure seating and perform a pressure test appropriate to the system to verify leak-free performance.

Usage recommendations

Use the reduced tee only within the pressure and temperature limits of the piping system and follow local plumbing codes. Store fittings away from prolonged UV exposure and avoid contact with aggressive solvents not recommended for polypropylene. For reliable results, use compatible PP pipe and approved joining materials and follow manufacturer guidelines for assembly and testing.
