What it is

The Buderus 7099165 O-ring is a 9.25mm x 1.78mm sealing ring supplied in a pack of 10. It is used to seal mating faces and connections on Buderus 600 series gas boilers, preventing water or gas from escaping at the joint. O-rings of this type are a service item and are commonly renewed during breakdown repairs and routine maintenance.

Signs this part needs replacing

  • Visible weeping or dripping at the joint the O-ring seals
  • Water staining, crusting or scale build-up around the sealing face
  • The O-ring has hardened, flattened or lost its flexibility
  • Cracks, splits or nicks visible on the ring
  • Discolouration or swelling of the rubber

Before you order

  • Confirm the existing O-ring dimensions match 9.25mm x 1.78mm
  • Check the appliance model against the fit list above
  • Note that this part is supplied as a pack of 10, so check how many seals the job requires
  • Inspect the sealing faces for damage before fitting, as a scored face will not seal with a new O-ring alone
