Product information

Description

TECE straight PPSU connector 20 x 16 mm is a straight transition fitting made from polyphenylsulfone (PPSU) for plumbing installations that join 20 mm and 16 mm pipes. The connector is designed for use in potable water and heating systems, offering a corrosion-resistant joint and mechanical stability appropriate for residential and commercial piping networks. Its straight form allows a simple inline connection when reducing from a larger to a smaller pipe diameter.

Advantages

The PPSU material provides high temperature resistance, good mechanical strength and chemical stability, reducing the risk of cracks or deformation under typical operational conditions. The straight 20 x 16 mm geometry enables a reliable reduction without requiring complex adapters. Corrosion resistance and suitability for potable water ensure long-term performance in water supply and heating circuits.

Suitable for

  • Reducing a 20 mm pipe to a 16 mm pipe in potable water systems
  • Inline transitions in domestic and commercial heating circuits
  • Repair or modification work where a compact straight reducer is needed

Key specifications

  • Material: polyphenylsulfone (PPSU)
  • Connection type: straight reduction fitting
  • Nominal diameters: 20 mm to 16 mm
  • Intended media: potable water and heating fluids
  • Application environment: residential and commercial plumbing systems

How to use

Prepare the pipes by cutting squarely and deburring the ends. Ensure pipe ends are clean and dry before assembly. Insert the 20 mm and 16 mm pipes into the corresponding ends of the straight connector according to the manufacturer’s assembly instructions for PPSU fittings, verifying a full engagement to form a sealed joint. Follow applicable codes for installation depth, support spacing and system pressure testing once assembled.

Usage recommendations

Use with compatible pipe systems and follow manufacturer guidance for temperature, pressure limits and installation technique. Avoid exposure to aggressive chemicals outside the intended media and perform pressure testing after installation to confirm leak-free connections.
