TECE Reducing Tee PPSU 25 x 16 x 25 mm, model 8711008

TECE Reducing Tee PPSU 25 x 16 x 25 mm, model 8711008 is a three-way plumbing fitting designed to create a reduced branch from two equal-diameter lines. Manufactured from PPSU (polyphenylsulfone), this reducing tee provides chemical and temperature resistance needed for potable water and heating installations. The fitting links two 25 mm runs with a central 16 mm outlet to form a compact and reliable branch connection in domestic and light commercial piping systems.

Advantages

The PPSU construction offers high mechanical strength, good dimensional stability and resistance to hot water and common plumbing chemicals. The reducing tee’s geometry ensures a smooth flow transition between the 25 mm main runs and the 16 mm branch, minimising turbulence and pressure loss. Its compact form factor simplifies installation in confined spaces and supports secure connections compatible with common joining methods used in modern piping systems.

Suitable for

• Domestic potable water distribution where a reduced branch is needed
• Hot water and heating circuits requiring sectional tap-offs
• Underfloor heating manifolds and compact riser installations
• Retrofit projects where space constraints require reduced fittings

Key specifications

• Material: PPSU (polyphenylsulfone) for chemical and thermal resistance
• Connection configuration: reducing tee with two 25 mm inlets/outlets and one 16 mm branch
• Application: potable water and heating systems
• Operating temperature range: suitable for typical hot water system temperatures
• Form factor: compact three-way fitting suited for confined installation spaces

How to use

Install the reducing tee in the pipeline where a 16 mm branch is required between two 25 mm runs. Prepare and cut pipes squarely and follow the chosen joining method’s instructions (e.g., press-fit, solvent welding, or compatible mechanical connector) to achieve leak-free joints. Ensure proper alignment and support of connected pipes to avoid stress on the fitting. Verify compatibility of sealing systems and joining tools with PPSU material before assembly.

Usage recommendations

For long-term performance, use the reducing tee within the intended temperature and pressure ranges of potable water and heating systems. Allow for thermal expansion in system design, avoid exposure to incompatible chemicals, and follow local plumbing codes and manufacturer guidance for installation and system testing.
