Product Description

For use in both house drainage and adoptable sewers compliant with water authority requirements, and adoptable by most water authorities that allow PVC-U pipework.

  • Easy push-fit installation with standard lubricant.
  • Integral ring seal quickens installation, increases seal quality, reduces delays & air test failure rates.
  • Safe and easy handling on site compared to alternative systems.
