Worcester Bosch Blanking Plug 15mm 87161065650

The Worcester Bosch 87161065650 is a 15mm blanking plug from the manufacturer's caps and plugs range. It closes off an unused tapping or connection point on the appliance, sealing the port so that water cannot escape and debris cannot enter the internal waterways. It is a small but load-bearing item: a blanking plug that has corroded or lost its seal will weep under system pressure, and the resulting loss of water is often the first thing an engineer notices on a service visit.

• A weep or drip at the blanking point, with water tracking down the pipework or casing
• Damp staining, rust bloom or white mineral crusting around the plug head
• Gradual loss of system pressure with no other visible leak on the appliance
• Corrosion or pitting on the plug body, or a plug that will not tighten down cleanly
• Evidence of the plug having been disturbed during earlier work and not resealed

• Check the GC number on the appliance data badge against the compatibility list to confirm the correct fitment
• Confirm the part number 87161065650 matches the item being replaced, and note the alternative number 1014967 where it appears on older documentation
• Check the sealing washer used with the existing plug is serviceable before refitting, and renew it if it is compressed or perished
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
