What it is

The Worcester Bosch RING-COMPRESSION 15MM is a compression fitting supplied by Worcester Bosch for use on 15 mm pipework. It is listed against oil boiler spares and is used within the hydraulic and water-carrying circuits of the appliances below. The fitting forms a mechanical seal by compressing an olive onto the pipe as the nut is tightened.

Signs this part needs replacing

  • Weeping or dripping at the compression joint when the system is under pressure
  • Damp staining, corrosion or limescale tracking around the nut and olive
  • The nut will not tighten down fully or has seized on the thread
  • A distorted or crushed olive that no longer seals against the pipe

Before you order

  • Confirm the pipework at the joint is 15 mm
  • Check the appliance model against the fit list above
  • Match the part number 87161402890 against the number on the existing component or parts listing
  • Ensure the joint can be isolated and drained before work starts
