What it is

The Worcester Bosch flange gasket G2.3.5, part number 87161072420, is a sealing component that fits at the flange joint on the appliance. It is listed by the manufacturer under gaskets, o-rings, seals and washers, and its role is to keep the mating faces of the flange sealed so the appliance continues to run reliably. The part is used across the Boulter Camray 5 family of oil-fired boilers.

Signs this part needs replacing

  • Visible weeping or staining around the flange joint
  • Gasket material that has hardened, flattened or cracked with heat and age
  • Water or oil residue tracking down the flange face
  • A recurring drop in system pressure or the need to top up more often than usual
  • A hot, oily or burning smell close to the joint when the appliance is running

Before you order

  • Check the appliance model and serial number against the compatibility list before ordering.
  • Confirm the gasket marking on the existing part matches G2.3.5.
  • Cross-reference alternative number 1021069 where that number appears on older paperwork or parts listings.
  • Assess whether the surrounding seals on the same joint also need renewing so the repair is completed in one visit.
