TECE PPSU Tee Fitting 20 x 16 x 16 mm - model 730508

TECE PPSU Tee Fitting 20 x 16 x 16 mm model 730508 is a three-way plumbing connector designed to create a T-branch between a 20 mm run and two 16 mm branches. Made from PPSU (polyphenylsulfone), this fitting is intended for use in potable water and building installations where resistance to temperature and chemicals is required. The fitting provides a compact, corrosion-resistant joint suitable for concealed or visible installation within plumbing and heating systems.

Advantages

The PPSU material delivers high mechanical strength and good dimensional stability at elevated temperatures, offering long-term performance in domestic and commercial piping. Its resistance to aggressive media and repeated thermal cycling reduces the risk of degradation compared with some other plastics. The tee fitting’s design enables secure connections between different pipe diameters without the need for metal adapters, helping to maintain system integrity and minimize potential galvanic corrosion.

Suitable for

• Domestic and commercial potable water distribution systems
• Underfloor heating manifolds and branch connections
• Applications requiring temperature and chemical resistance
• Concealed installations in walls, ceilings, and service cavities

Key specifications

• Material: PPSU (polyphenylsulfone) for enhanced thermal and chemical resistance
• Connection configuration: T-branch (one inlet, two outlets)
• Pipe sizes: main run 20 mm; branch connections 16 mm
• Application: potable water and building service installations
• Mechanical properties: high impact strength and dimensional stability at elevated temperatures

How to use

Select compatible 20 mm and 16 mm pipes made from materials recommended by the system manufacturer. Prepare pipe ends by cutting square and removing burrs, then insert to the specified depth according to the pipe system’s joining method. Ensure connections are executed per TECE installation instructions and local plumbing codes. After assembly, perform pressure testing and visual inspection to confirm leak-tight joints before concealing the installation.

Usage recommendations

Use this PPSU tee in systems where potable water approval and elevated temperature performance are required. Avoid exposure to solvents not recommended for PPSU and follow TECE’s guidance for compatible pipe materials and maximum operating temperatures. Regularly inspect accessible installations and verify that installation clearances comply with local standards.
