What it is

The Worcester Bosch Gasket - Valve is a sealing component supplied under part number 87161120830 by Worcester Bosch. It seats at the valve joint to maintain a leak-free seal on the appliance. It is used across a number of Worcester Bosch Greenstar oil-fired boiler ranges.

Signs this part needs replacing

  • Weeping or visible water or oil traces at the valve joint
  • Damp staining or corrosion around the gasket face
  • Gasket hardened, flattened or cracked when the joint is opened
  • Gasket damaged or torn during valve removal or servicing
  • Persistent small leak at the valve connection after tightening

Before you order

  • Confirm the part number 87161120830 matches the one on the existing component or the appliance literature
  • Check the boiler model against the fitment list before ordering
  • Inspect the valve body and mating face for scoring or damage that a new gasket alone will not correct
  • Confirm whether a full valve assembly is required instead of the gasket
