What it is

This is a Buderus sealing component with the supplied dimensions of 4mm x 21mm x 30mm, supplied as a pack of five under part number 7098962. It is a sealing washer used in the assembly of Buderus gas boilers, where it seals a joint against water or gas loss. The part sits within the O-rings, washers and gaskets category of gas boiler spares.

Signs this part needs replacing

  • Visible water or gas weeping at the sealed joint

  • Flattening or deformation of the seal so it no longer seats correctly
  • Traces of scale, corrosion or residue around the sealing face after dismantling
  • The joint fails to seal after the appliance has been reassembled

Before you order

  • Check the existing seal dimensions against the 4mm x 21mm x 30mm stated for this part
