What it is
A pack of 10 O-rings manufactured by Glow-worm under part number 0020018487. These seals are used at joints and connections across a wide range of Glow-worm gas boiler models. They form the watertight and gas-tight seal at the point of fitment.
Signs this part needs replacing
- Water weeping or traces of residue around a joint or connection
- The O-ring has hardened, flattened or lost its elasticity
- Visible cracking, splitting or deformation of the ring
- A joint that continues to leak after being re-tightened
- Scale or corrosion build-up on the seal seating
Before you order
- Confirm your boiler model against the fitment list above
- Check how many O-rings the job requires against the pack quantity
- Inspect the seal seating for damage or corrosion before fitting
- Verify the part number 0020018487 matches the one removed
