Uponor PEX Q&E Shrink-Fit System

Uponor PE-X pipe – The world’s first, best and most widely used

Ideal for both commercial and domestic plumbing installations, Uponor’s PE-X  Quick & Easy system can be used for the hygienic delivery of drinking water, heating systems and chilled water systems. It has been tested to many national and international standards and holds full UK WRAS certification.

There are currently three different methods for manufacturing PE-X, known in the industry as PE-Xa, PE-Xb and PE-Xc:

PE-Xa (Peroxide)- 70% (Uponor PE-Xa up to 85%) crosslinking

PE-Xb (Silane)- 65% crosslinking

PE-Xc (Electron Beam)- 60% crosslinking

What really separates Uponor PE-Xa pipe from the competition is its high degree of crosslinking. This ensures greater flexibility in tight installation spots and better resistance to stress than either PE-Xb or PE-Xc pipe materials.


Application areas:


  • Tap water connections
  • Radiator connections
  • Ideal for new builds and renovations




  • Uponor PE-Xa Combi pipe- 12-63mm

Manifold installation

Manifold installation

Aqua PLUS PPM manifold

Manifold plumbing is becoming more and more popular as designers are having to supply warm water faster than ever before. Many building specifications require completely joint-free connections from the point of supply, to the point of use. When required, individual isolation valves allow perfect control of each outlet, without affecting the rest of the system.

Easy and quick installation with no ‘in wall’ connections
