PPSU Reducing Tee TECE 25 x 20 x 25 mm – plumbing fitting

Reducing tee in PPSU material by TECE with dimensions 25 x 20 x 25 mm. This plumbing fitting is engineered to create a secure branch from a 25 mm main run to a 20 mm service line. Made from high-performance PPSU thermoplastic, the fitting offers chemical and temperature resistance suitable for potable water and many heating installations. Its compact reducing design is intended for use in pipework transitions, distribution manifolds and repair situations where a reliable, corrosion-resistant junction is required.

Advantages

The TECE reducing tee manufactured from PPSU combines long-term dimensional stability with resistance to scaling and aggressive media. The material provides good impact strength and maintains mechanical properties at elevated temperatures typical for hot-water systems. The reduced centre outlet allows straightforward integration into existing 25 mm networks while producing a tight fit for 20 mm branch lines. The product is lightweight, non-corroding and requires minimal maintenance once installed.

Suitable for

• Branching potable water supply from 25 mm mains to 20 mm service lines
• Connections within distribution manifolds and compact installations
• Repairs and alterations in domestic and commercial plumbing
• Applications where corrosion resistance and chemical stability are required

Key specifications

• Material: PPSU thermoplastic
• Dimensions: 25 x 20 x 25 mm (main run x branch x main run)
• Application: potable water and compatible heating systems
• Design: reducing tee for creating a 20 mm branch from a 25 mm main
• Properties: corrosion-resistant, impact-resistant, temperature-stable within typical plumbing ranges

How to use

Prepare the pipe ends by cutting square and deburring to ensure a smooth joint. Insert the 25 mm main pipes and the 20 mm branch pipe into the respective ports of the reducing tee, following the installation method specified for the chosen piping system (for example solvent weld, press-fit, or push-fit if compatible). Ensure correct alignment and engagement depth so that seals or fittings seat properly. After assembly, verify the installation by performing a pressure test according to local plumbing standards and inspect all joints for leaks before handing over the system.

Usage recommendations

Use the fitting only with compatible pipe materials and installation methods suitable for PPSU. Observe system temperature and pressure ratings applicable to potable water and heating circuits. Where required, follow local plumbing codes for support spacing and thermal expansion allowances. Store the component away from prolonged UV exposure and extreme temperatures prior to installation.
