What it is

The Worcester Bosch 87161083880 is a 10-litre expansion vessel used in the manufacturer's oil boiler range. It absorbs the volume increase of water as the heating system heats up, limiting pressure rise and protecting components such as the pressure relief valve. It is listed under oil boiler spares for the CAM 5 and Camray families.

Signs this part needs replacing

  • System pressure rises quickly when the boiler heats up and falls when it cools.
  • The pressure relief valve discharges water during normal operation.
  • The boiler loses pressure and requires frequent topping up.
  • Visible corrosion or water is present at the vessel connection.

Before you order

  • Confirm the appliance model against the fit list above.
  • Check the existing expansion vessel is rated at 10 litres.
  • Verify the part number 87161083880 is correct for the boiler.
  • Inspect the system for other causes of pressure loss before replacing the vessel.
