What it is
An O-ring supplied by Glow-worm under part number 0020125437. It is a circular elastomer seal that sits in a mating joint to prevent leakage from the connection it seals. This part is listed for the Glow-worm Energy 35 Store boiler.
Signs this part needs replacing
- Water weeping or a visible drip at the joint the O-ring seals
- A gas smell or a detected leak at the joint — isolate the appliance and call a Gas Safe registered engineer
- The ring looks flattened, cracked, hardened or swollen
- Discolouration, corrosion or damp staining around the joint
- The joint continues to leak after being re-tightened
Before you order
- Check the appliance data badge to confirm the exact model and GC number
- Confirm the part number against the manufacturer's parts list for your appliance variant
- Inspect the joint for other worn seals, washers or gaskets that may also need replacing
