What it is
The Worcester Bosch 87302039980 is a sealing washer from the manufacturer's gaskets, O-rings, seals and washers range. It is used across the Greenstar family and the British Gas-badged equivalents of those appliances. Its job is to seat between mating faces and close the joint against water or system pressure, so a worn or flattened washer is a common cause of weeping connections.
Signs this part needs replacing
- Water weeping or dripping from the joint the washer seals
- The washer looks flattened, hardened or cracked once removed
- Scale, sludge or corrosion deposits built up around the sealing face
- A damp patch or staining beneath the appliance
- Slight seepage reappearing after a component has been stripped and refitted
Before you order

- Cross-reference the previous number DD97904247 and the alternative number 1020271 against the part being replaced.
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
