What it is

The Worcester Bosch 87161409180 is a thin-profile washer measuring 22mm, used as a sealing component within the water-carrying and hydraulic assemblies of Worcester Bosch appliances. It sits between mating faces to create a watertight joint and is classed by the manufacturer as part of the gaskets, seals and washers group. It is a service item, so it is normally replaced whenever the joint it seals is disturbed.

Signs this part needs replacing

  • Water weeping or a visible drip at the joint the washer seals
  • Staining, crusting or limescale tracking around a union or connection
  • The washer has flattened, hardened or cracked after long service
  • A leak reappears shortly after a repair where the old washer was reused
  • Damp patches or corrosion on nearby metalwork below the joint

Before you order

  • Check the GC number and model plate on the appliance against the compatibility list before ordering, as several Heatslave and Highflow variants use different sealing arrangements.
  • Confirm the part number 87161409180 or the alternative number 1017623 matches the item being replaced.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
