TECE reducing tee PPSU 25 x 20 x 20 mm, model 8711009

TECE reducing tee in PPSU material, 25 x 20 x 20 mm, is a three-way plumbing fitting designed to join a main run with a smaller branch. Manufactured from PPSU (polyphenylsulfone), this reducing tee provides chemical and temperature resistance suitable for potable water and heating systems. The part is intended for use in distribution, new installations and repair work where a reliable transition between different pipe diameters is required.

Advantages

The PPSU construction offers high resistance to hot water, chemicals and steam, ensuring long-term dimensional stability and reduced risk of deformation. The compact reducing design enables a smooth hydraulic transition between pipe sizes while maintaining flow characteristics. Made to TECE standards, the fitting is compatible with common piping systems and installation methods, providing consistent sealing performance and mechanical durability.

Suitable for

• Potable water distribution in residential and commercial buildings
• Heating systems and hot water circuits
• Repair and retrofit work where diameter reduction is needed
• Distribution manifolds and branch connections

Key specifications

• Material: polyphenylsulfone (PPSU) for improved heat and chemical resistance
• Connection layout: reducing tee with one larger inlet and two smaller outlets/branches
• Nominal dimensions: main run 25 mm, branch connections 20 mm
• Application: potable water and heating systems
• Operating temperature range: suitable for typical hot water and heating temperatures (refer to system design limits)

How to use

Select the appropriate pipe types and connection methods compatible with PPSU fittings and the specified diameters. Prepare pipe ends by cutting square and deburring, then assemble according to the chosen joining technique (mechanical push-fit, welding or approved connection specified for the piping system). Ensure correct alignment before finalizing the connection and perform pressure testing as required by local regulations to verify sealing and mechanical integrity.

Usage recommendations

Use with pipes and installation components rated for PPSU fittings and the same temperature and pressure class. Verify compatibility with the system’s sealing method and follow national plumbing codes for potable water and heating installations. Avoid exposing the fitting to unsupported chemical agents outside typical potable water and heating environments.
