## Long 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
