What it is

The Blanking Olive 15mm is a Worcester Bosch sealing component supplied under part number 87161134410. It is fitted where a 15mm pipe connection is blanked off, forming a compression seal between the pipe and the fitting. It is used on Worcester Bosch Greenstore combi boiler installations.

Signs this part needs replacing

  • Weeping or a visible water trace at a blanked-off 15mm connection
  • The olive is crushed, split or visibly deformed after tightening
  • The olive has been reused after being compressed and will not seal again
  • Corrosion or pitting on the olive surface where it meets the fitting

Before you order

  • Confirm the pipe size at the blanking point is 15mm.
  • Check the appliance model against the fit list above.
  • Inspect the fitting and nut for damage before refitting, as a scored seat will not seal even with a new olive.
