New PolyPlumb® Push-Fit System. New Look and feel.


For 25 years, PolyPlumb® has served as a tried and tested staple of the residential plumbing market. Our original, robust and reliable grey push-fit plumbing system, PolyPlumb® continues to be one of the most popular fittings for plumbing professionals.

As we strive to push the boundaries of innovative technology and progressive design, the PolyPlumb® system you know and love has been improved. Now updated with a fresh new look and patented In-Cert® feedback technology, the new PolyPlumb® Enhanced fitting continues to deliver the reliability and confidence you’ve grown to expect from Polypipe Building Products.

PolyPlumb® Enhanced fittings still feature the same robust stainless-steel grab ring and pre-lubricated EPDM O-ring that’s been at the heart of the fitting, which is now available in grey and white! Grab a FREE sample at

PolyPlumb® Enhanced: FIT WITH CONFIDENCE.

The PolyPlumb® plumbing system you know, and love has been enhanced. Now updated with a new streamlined design and patented In-Cert® feedback technology, the new PolyPlumb® Enhanced fitting continues to deliver the reliability you’ve grown to expect.

Improved jointing confidence with In-Cert®

PolyPlumb® Enhanced features our patented In-Cert® Pipe Stiffener, providing you with improved jointing confidence and peace of mind through haptic feedback. The In-Cert® is manufactured from a high specification engineering polymer which is used in demanding automotive, aerospace and medical applications.

The new patented In-Cert® incorporates a 360o wave feature in its head which engages with projections within the socket. The haptic click of the In-Cert® technology gives real confidence; just push the pipe home, twist and you know the jobs’ done; PUSH, TWIST, KNOW. It really is that easy.

A range of benefits at your fingertips. PolyPlumb® Enhanced is suitable for use in most plumbing and heating installations, including hot and cold water and underfloor heating applications.

The system offers a number of benefits:

  • Our enhanced original grey plumbing system, using tried and tested technology for 25 years.
  • PolyPlumb® Enhanced provides a superb combination of fast fitting with a permanent, reliable fix – now with patented In-Cert® feedback technology.
  • Polyplumb® Enhanced provides joint integrity, assured by a robust stainless steel grab ring.
  • Secure; demountable by disassembly only. (click here to read more about the simple and secure fitting)
  • Reduced plastic packaging (click here to read more about our Packaging that Cares)
  • Use with Polypipe grey and white plumbing and heating pipe or copper pipe.
  • Use with new patented In-Cert® feedback technology Pipe Stiffeners for added confidence.
  • 50-year guarantee.

Our most versatile fitting yet.

PolyPlumb® Enhanced fittings are suitable for use with Polypipe grey and white plumbing and heating pipe. Grey and white systems are fully compatible with
each other if required. The fittings also joint seamlessly with copper pipe (no Pipe Stiffener needed).

Our original metal and plastic Pipe Stiffeners can still be used with our plumbing and heating pipe and the new PolyPlumb® Enhanced fitting. You can use the InCert® Pipe Stiffener with the original version of PolyPlumb® too. However, you won’t get the benefit of the In-Cert® feedback technology with these combinations. For confidence always use the patented In-Cert® with PolyPlumb® Enhanced.
