What it is
The O-Ring NBR 29mm x 2mm is a nitrile rubber sealing ring supplied by Worcester Bosch in a pack of 10. It is used to seal mating faces and connections on Worcester Greenstar combi and system boilers, keeping the water circuit tight at the joint it sits in. The ring is a service item, so it is worth holding a pack for routine maintenance and repair work.
Signs this part needs replacing
- Water weeping or a visible drip at a joint sealed by the O-ring
- A flattened or hardened ring that no longer sits proud of its groove
- Cracking, swelling or surface deterioration on the ring
- Scale, sludge or debris trapped on the sealing face causing a poor seal
- Reassembly work where the existing ring has been disturbed or removed
Before you order
- Confirm the part number 87186626260 matches the ring being replaced
- Check the appliance model against the fit list above
- Check how many rings the job needs — this pack contains 10
- Inspect the groove and sealing face for damage before fitting a new ring
