What it is
This is a Worcester Bosch rubber seal, supplied under part number 87161131210. It is a sealing component used on Worcester Greenstar Heatslave External and Heatslave II EXT oil-fired boiler ranges, where it forms a watertight or airtight joint at the point of fitment. Seals of this type are service items and are renewed when the existing seal has hardened, perished or begun to weep.
Signs this part needs replacing
- Visible weeping or dripping at the joint the seal serves
- Water staining, corrosion or scale build-up around the sealing face
- The seal has hardened, flattened or lost its elasticity
- Cracking, splitting or deformation visible on the rubber
- A leak that reappears after the joint has been re-tightened
Before you order
- Confirm the boiler model and GC number against the data badge before ordering
- Check the part number 87161131210 matches the number on the existing seal or in the boiler literature
- Inspect the sealing face for pitting or corrosion, as a damaged face will not seal even with a new seal
- Note that seals are often replaced during a service or repair, so check whether other seals in the same assembly also need renewing
