What it is
The Seal, part number 8716121856, is a Worcester Bosch sealing component used within Greenstar 2000 and Greenstar 4000 series gas boilers. It forms a fluid-tight joint at its designated location in the appliance, preventing water or gas escape where components meet. It is supplied as a single seal.
Signs this part needs replacing
- Visible water weeping or dripping from the joint the seal serves
- Water staining, corrosion or limescale tracking around the sealing face
- The seal has hardened, flattened or cracked with age and no longer sits proud of its groove
- A leak reappears shortly after the joint has been reassembled
- The seal was disturbed during servicing and does not seat cleanly on refitting
Before you order
- Confirm the appliance model and GC number against the fit list above
- Check the part number 8716121856 matches the seal currently fitted
- Identify the exact position of the seal on the appliance before removal so it can be refitted correctly
- Inspect the mating faces for damage or corrosion, as a new seal will not correct a scored or distorted joint
