What it is

The Buderus sealing lipring is a moulded rubber seal measuring DN36.4 mm x 24.4 mm x 6.3 mm, supplied as a set of two pieces under part number 7099794. It is used on Buderus 500 and 600 series gas boilers to seal a joint against water or gas leakage at the point of assembly. The lip profile seats against the mating face as the component is tightened, restoring a fluid-tight seal.

Signs this part needs replacing

  • Visible water or fluid weeping around the sealed joint
  • Hardening, cracking or flattening of the rubber lip
  • Scale or corrosion staining tracking from the joint face
  • Loss of elasticity so the lip no longer springs back against its seat
  • Seal disturbed or pinched during previous work on the joint

Before you order

  • Confirm your appliance model against the fits list above before ordering
  • Compare the failed seal's dimensions and lip profile with the dimensions given here
  • Check how many seals the joint requires, as the pack contains two pieces
  • Inspect the mating faces for scoring or pitting that would prevent the new seal seating
