What it is

The Vokera 7999 is a small rubber O-ring used as a sealing component within the hydraulic and water-carrying sections of Vokera gas boilers. It is supplied as a pack of ten. The O-ring seals mating surfaces and connections to prevent water weeping or dripping from the joint.

Signs this part needs replacing

  • Water weeping or dripping from the joint the O-ring seals
  • The O-ring is visibly flattened, hardened or cracked
  • Scale or corrosion deposits around the sealing face
  • Water staining or residue on components below the joint
  • A joint that continues to seep after the retaining nut or fitting has been tightened

Before you order

  • Confirm your boiler model and, where relevant, the serial number range (Mk1, Mk2 or Mk3) against the fitment list
  • Check the manufacturer's parts list to confirm the O-ring is the correct item for the joint being repaired
  • Confirm how many O-rings the job requires, as the part is supplied in a pack of 10
