What it is

The Regin O-Ring (Imperial) is a sealing ring sized 1 1/8" x 1/8" (28.17mm x 3.53mm), supplied in a pack of 10. It is used to form a leak-tight seal at joints and connections on Regin consumables and BITS N Bolts assemblies. The ring compresses between mating surfaces to stop water escaping from the joint.

Signs this part needs replacing

  • Visible cracking, splitting or perishing of the rubber
  • Hardened or brittle feel when handled
  • Flattened or deformed cross-section that no longer seals
  • Weeping or dripping at the joint the O-ring sits in
  • Water tracking or staining around the connection

Before you order

  • Confirm the O-ring dimensions match the one being replaced (1 1/8" x 1/8" / 28.17mm x 3.53mm)
  • Check the pack quantity suits the number of joints being serviced
  • Verify the part is suitable for your Regin appliance or assembly
