Tee fitting TECE PPSU 25 x 16 x 20 mm model 730544 for plumbing connections

TECE PPSU tee fitting 25 x 16 x 20 mm model 730544 is a three-way pipe connector designed for branching and distribution in potable water and heating systems. Manufactured from PPSU (polyphenylsulfone), this fitting combines high mechanical strength, elevated temperature resistance and long-term dimensional stability to support reliable connections in domestic and light commercial plumbing installations.

Advantages

The PPSU material provides excellent resistance to heat, hydrolysis and many chemicals, reducing the risk of deformation or failure under typical operating conditions. The three-way configuration with diameters 25 × 16 × 20 mm allows direct transitions between different pipe sizes without additional adapters. Corrosion-free construction and smooth internal surfaces support consistent flow and reduced scaling over time.

Suitable for

• Potable water distribution in residential buildings
• Domestic heating circuits and manifold connections
• Pipe branching where different diameters must be joined (25 mm to 16 mm and 20 mm)
• Applications requiring chemical and hydrolysis resistance

When it may not be suitable

This fitting is not intended for direct use in high-pressure industrial processes exceeding typical plumbing system ratings. It may be unsuitable where metallic fittings are specifically required for mechanical fastening, grounding or where regulatory codes mandate metal components.

Key specifications

• Material: PPSU (polyphenylsulfone)
• Connection type: three-way tee
• Nominal diameters: 25 mm × 16 mm × 20 mm
• Typical applications: potable water and heating systems
• Properties: corrosion-resistant, hydrolysis-resistant, high-temperature stability

How to use

Install the tee fitting in accordance with the pipe system manufacturer's instructions and local plumbing codes. Prepare pipe ends by cutting square and deburring, then insert to full depth according to the connection method recommended for the specific pipe material (e.g., press-fit, socket fusion or push-fit where applicable). Ensure proper alignment and support nearby pipelines to avoid stress on the fitting. Perform pressure testing after installation as required by standards.

What to consider before purchase

• Verify compatibility of connection method with your existing pipe and installation tools
• Confirm that the diameters 25 × 16 × 20 mm match the pipes in your system
• Check local building codes for material and component requirements

Usage recommendations

Use this TECE PPSU tee fitting in potable water and heating installations where plastic fittings are accepted; follow manufacturer installation guidelines and perform standard leak and pressure tests after fitting installation.
