What it is
The Worcester Bosch 87161057680 is a silicone sponge sealing component used in the Worcester 28i Junior RSF family of gas boilers. It belongs to the gaskets, O-rings, seals and washers group of spares, and its soft, compressible silicone construction allows it to seat against mating surfaces where a firm rubber seal would be unsuitable. It is a service item, so it is replaced whenever the surrounding assembly is opened or disturbed.
Signs this part needs replacing
- Visible compression set, crumbling or breakdown of the sponge material when the assembly is opened
- Traces of water or flue gas weeping past the joint the seal is meant to close
- Discolouration, hardening or flattening of the silicone where it contacts the mating face
- The seal is disturbed or damaged during routine servicing and cannot be reused
- Reassembly leaks that persist after the housing has been correctly torqued down
Before you order
- Confirm the appliance GC number and model against the compatibility list, as the 28i Junior RSF was produced in several variants
- Check the existing part number on the component being replaced before ordering, and cross-reference it with 1014725
- Assess whether the surrounding gasket or seal kit also needs renewing at the same time
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
