PPSU reducer tee TECE 25 x 16 x 16 mm model 8711007 for plumbing connections

PPSU reducer tee TECE 25 x 16 x 16 mm model 8711007 is a plumbing fitting designed to join a 25 mm supply line to two 16 mm branches. Manufactured from high-performance PPSU (polyphenylsulfone), the fitting is intended for use in hot and cold water distribution systems where differing pipe diameters must be connected. The compact tee provides a stable transition between pipe sizes while maintaining flow integrity and resistance to temperature and common plumbing chemicals.

Advantages

The PPSU material delivers good mechanical strength and long-term dimensional stability at elevated temperatures. The reducer tee supports secure, leak-resistant connections when installed with compatible push-fit or compression systems and is resistant to deformation under pressure. Its compact form factor simplifies installation in confined spaces and reduces the need for additional adapters or couplings.

Suitable for

• Domestic hot and cold potable water supply lines
• Branching a 25 mm main feed to two 16 mm feed lines for fixtures
• Installation in underfloor heating manifolds where compatible pipe sizes are used
• Plumbing repairs and retrofit work requiring a size transition

Key specifications

• Material: PPSU (polyphenylsulfone) suitable for potable water
• Connection configuration: one 25 mm inlet to two 16 mm outlets
• Application temperature: suitable for typical hot and cold water ranges (compatible with potable hot water systems)
• Pressure handling: engineered for standard domestic plumbing system pressures
• Compact dimensions designed for tight installation spaces

How to use

Before installation, verify compatibility with the piping system and any seals or connection method required by the chosen installation technique. Cut and prepare pipe ends squarely, deburr and clean to ensure proper seating. Install the reducer tee according to the pipe system manufacturer’s instructions, using the appropriate joining method for PPSU parts and the connected pipes (for example, push-fit, compression fittings or system-specific connectors). After assembly, perform a pressure test according to local plumbing codes to confirm leak-free operation.

Usage recommendations

Use the fitting only with compatible pipe materials and joining systems approved for PPSU components. Avoid exposing the fitting to chemicals or conditions outside normal potable water service. Follow local regulations for potable water installations and perform pressure and leak testing after installation to ensure reliability.
