What it is

This is an O-ring supplied by Glow-worm under part number 0020195540. It is a sealing component used within the hydraulic assemblies of Glow-worm gas boilers, where it prevents water from escaping at a joint or connection. It is listed for use across the Energy, Energy7, HOME, Sustain, Easicom and Ultimate appliance families.

Signs this part needs replacing

  • Water weeping or dripping from the joint the O-ring seals
  • The O-ring is visibly flattened, hardened or cracked
  • Scale, sludge or debris is embedded in the seal surface
  • A joint that continues to seep after being tightened
  • Repeated pressure loss traced to a sealed connection

Before you order

  • Confirm your boiler model and GC number against the manufacturer's parts list
  • Check that the part number quoted for your appliance is 0020195540
  • Inspect the mating surfaces and housing for scoring or corrosion before fitting a new seal
  • Check whether other seals in the same assembly also need replacing
