Hep2O | Professional push-fit plumbing system

For speed, ease and reliability.
It must be Hep2O.

Why Hep2O

Hep2O is not just designed to perform, it’s built to last with a 50 year guarantee (twice as long as anyone else). The slim and sleek fittings work with both plastic or copper pipe and are ideal for a range of hot and cold water and heating applications.

All fittings feature unique In4sureTM joint recognition technology which tells you when a secure joint has been made. And if you need to adjust things onsite, HepKeyTM unlocks the tamper-proof fittings, making demounting simple. No wonder it’s the only plastic system approved by British Gas and used by 70% of major UK house builders.

  • Comprehensive range of fittings to suit every job
  • 50 year guarantee
  • Secure joint recognition with In4sureTM technology
  • Demounting made easy with the handy HepKeyTM

Anything else is just a fitting
