PPSU Reducing Tee TECE 20 x 25 x 20 mm, model 8711011

PPSU reducing tee TECE 20 x 25 x 20 mm is a three-way plumbing fitting designed to join pipes with a reduced central branch. Manufactured from polyphenylsulfone (PPSU), the fitting offers high resistance to heat and common plumbing chemicals, making it suitable for potable water and heating installations where a reliable, dimension-reducing branch is required. The product establishes a 20–25–20 mm reduction and supports straightforward integration into push-fit or compatible connection systems used in modern installations.

Advantages

The PPSU construction provides good mechanical strength, long-term durability and resistance to repeated thermal cycles. Chemical resistance and stability at elevated temperatures reduce the risk of deformation or premature aging in hot water and heating circuits. The compact design facilitates space-efficient branching and simplifies installation, while material properties ensure compatibility with potable water regulations and common system fluids.

Suitable for

• Domestic and commercial potable water distribution
• Heating systems and radiant floor heating manifolds
• System extensions, retrofits and repairs requiring a 20–25–20 mm reduction
• Plumbing applications where chemical and temperature resistance are needed

Key specifications

• Material: Polyphenylsulfone (PPSU)
• Connection arrangement: reducing tee with central branch
• Nominal dimensions: 20 mm x 25 mm x 20 mm (branch reduction)
• Application: potable water and heating systems
• Temperature resistance: suitable for hot water and heating circuit temperatures (manufacturer PPSU class performance)

How to use

Prepare compatible pipes by cutting square and deburring the ends, then insert the pipes into the tee according to the system’s connection type (push-fit or manufacturer-recommended fittings). Ensure correct insertion depth and, if applicable, follow any sealing or retaining instructions from the connection system. After assembly, pressure-test the system in accordance with local standards to verify leak-tightness before commissioning.

Usage recommendations

Use this reducing tee in applications that match its dimensional and material properties, avoid exposing it to unsupported chemical agents outside typical potable water and heating fluids, and follow system manufacturer installation guidelines to ensure long-term performance.
