What it is

The Glow-worm O-ring S212322 is a sealing component used in Glow-worm Compact 75E, 80E and 100E gas boilers. It sits at the joint where it is fitted and forms a watertight seal, preventing leaks from that connection. The part is identified by the Glow-worm part number S212322.

Signs this part needs replacing

  • Water weeping or dripping from the joint where the O-ring sits
  • Visible cracking, flattening or perishing of the rubber
  • The O-ring has hardened or lost its elasticity
  • Scale or corrosion deposits around the seal
  • Damp staining or residue on nearby components

Before you order

  • Confirm your boiler is one of the Compact 75E, 80E or 100E models listed above
  • Check the GC number on the appliance data badge against your model
  • Verify the part number S212322 matches the component being replaced
  • Isolate the water and gas supplies before removing the existing O-ring
