What it is

The Regin O-Ring (Metric) 38mm x 4.0mm is a metric sealing ring supplied in a pack of nine. It forms a seal at the point of fitment on Regin BITS N Bolts and Regin Consumables.

Signs this part needs replacing

  • Water weeping or dripping from the joint the O-ring seals
  • Cracking, splitting or perishing of the rubber
  • The O-ring has flattened or hardened and no longer sits proud of its groove
  • Water staining or scale around the fitting
  • Leaks that return after the joint is tightened

Before you order

  • Measure the old O-ring and confirm the 38mm x 4.0mm size
  • Check the cross-section suits the groove it sits in
  • Confirm how many O-rings the job requires
  • Check your appliance model against the manufacturer's parts list
