What it is

This is a Worcester Bosch O-ring supplied under part number 87002050010. It is a circular elastomer seal used to close the joint between mating components inside the appliance, preventing water or gas from escaping past the connection. It is listed against Worcester Bosch Greenstar, W135 series and British Gas Jetatherm appliances.

Signs this part needs replacing

  • A visible weep or drip at the joint the O-ring seals
  • The ring has hardened, flattened or cracked with heat ageing
  • Water staining, corrosion or scale around the mating faces
  • A faint gas smell or a detected leak at a sealed connection
  • The seal is damaged or stretched after the joint has been opened for servicing

Before you order

  • Check the appliance GC number and serial plate against the compatibility list before ordering, as several W135 and Greenstar variants use different seals.
  • Confirm the number on the old component matches 87002050010 or the alternative number 1011691.
  • If the joint is being opened for a repair, check whether a full gasket or seal kit is needed rather than a single ring.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
