Worcester Bosch O-Ring 2.62 x 15.54mm ID 87161408050

This is a Worcester Bosch O-ring with a 2.62mm cross-section and a 15.54mm internal diameter, supplied under part number 87161408050. It is a sealing component used at a joint or connection inside Worcester Bosch appliances, where it compresses to stop water or gas escaping past the mating faces. O-rings of this size are typically found at small bore connections, sensor pockets and internal unions, and they are a service item that degrades with heat cycling and age.

• A weep or drip at the joint the O-ring seals, often showing as water staining or crusting around the connection
• The ring has hardened, flattened or gone brittle with heat cycling, so it no longer springs back when compressed
• Visible splits, nicks or a flattened cross-section on inspection once the joint is opened
• Scale or corrosion debris sitting in the seal groove, preventing the ring from seating properly
• A joint that has been disturbed and will not seal again on reassembly with the original ring

• Check the GC number and appliance serial plate against the compatibility list to confirm this O-ring suits your model
• The alternative number 1017537 may be marked on older documentation or parts listings for the same item
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
• Inspect the seal groove and mating faces before fitting, and replace the ring if it has been compressed or contaminated during the repair
