What it is
The Worcester Bosch 87161408480 is a small O-ring seal with a 2.5mm x 10mm cross-section, moulded in EP50 rubber. It sits in a machined groove and compresses between two mating faces to stop water escaping from the joint it serves. It is a service item, renewed whenever the joint is opened or the ring has hardened, flattened or cracked.
Signs this part needs replacing
- Water weeping or a visible drip at the joint the O-ring seals
- The ring has hardened, flattened or lost its round cross-section
- Cracks, splits or a shiny, compressed face on the rubber
- Scale or corrosion debris sitting in the seal groove
- A joint that still seeps after being cleaned and re-tightened

- If the appliance is being stripped down for other work, check whether other seals in the same assembly also need renewing.
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
