What it is
The Worcester Bosch O-ring 87161067500 is a nitrile sealing ring used in the gas assembly of Greenstar and Greenstar ErP boilers. It sits between mating components to stop gas and water escaping at the joint. Seals of this type are used in several areas of the boiler, including heat exchangers and gas valves, wherever parts meet pipework or another component.
Signs this part needs replacing
- A gas smell or a detected leak traced to a gas assembly joint
- Water weeping, drips or staining around a heat exchanger or gas valve connection
- The O-ring is visibly hardened, flattened, cracked or perished on inspection
- The seal was disturbed or damaged during a service or component change
- Repeated pressure loss traced to a joint rather than to the appliance itself
