What it is

The Worcester Bosch O-Ring 12.5mm x 3mm is a circular elastomer seal used to make a watertight joint between mating components inside Worcester Bosch gas boilers. It is a service part for the Worcester Bosch and British Gas Greenstar ranges, including the 430/I and 532/I families. The ring sits in a machined groove and is compressed as the joint is assembled, sealing the connection against water and heating circuit pressure.

Signs this part needs replacing

  • Water weeping or a visible drip at the joint the ring seals
  • Limescale or corrosion staining around the joint face
  • The ring feels hard, flattened or brittle instead of pliable
  • Cracks, nicks or a flattened cross section visible once removed
  • Repeated pressure loss on the heating or domestic hot water circuit

Before you order

  • Check the GC number or serial plate on the appliance to confirm the correct ring for your model.
  • Compare the previous part numbers 8-716-115-679-0 and 87161156790 against the component being replaced.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
