What it is

The Regin REGQ123 is a 3/4" cap and lining washer supplied in a pack of 20. It sits at the cap and lining joint to form a watertight seal, and forms part of the Regin consumables range of fixings and fittings for heating and plumbing work.

Signs this part needs replacing

  • Weeping or dripping at the cap and lining joint
  • Water staining or scale build-up around the washer seating
  • Washer hardened, cracked or flattened with age
  • Repeated re-tightening needed to stop a leak
  • Washer split or deformed on removal

Before you order

  • Confirm the washer size required is 3/4"
  • Check how many washers are needed against the pack quantity of 20
  • Inspect the cap and lining faces for damage before fitting
