What it is
The Glow-worm S208040 is an O-ring for a gas valve. It is used in Glow-worm gas boilers, including combi, economy and fuel saver appliance families. The O-ring provides a seal at the gas valve connection.
Signs this part needs replacing
- Visible cracking, flattening or hardening of the O-ring
- Gas smell or leak detection at the gas valve joint
- Weeping or residue around the gas valve connection
- Failed gas tightness check on the gas valve assembly
- O-ring missing or damaged during gas valve service
Before you order
- Confirm the part number S208040 matches the existing O-ring or the manufacturer's parts list.
- Check the appliance model and GC number against the fitment list.
- Measure the old O-ring to confirm the 22.0 x 2.5 size if dimensions are not legible.
