What it is

The Baxi 7805335 is a seal gasket manufactured by Baxi for use in its Assure and HP40/HP50 appliance families. It forms the sealing element at the joint it is fitted to, preventing water or flue gas leakage depending on its location in the appliance. It is a service part intended for replacement during maintenance or repair work.

Signs this part needs replacing

  • Visible water weeping or damp staining around the joint the gasket seals
  • The gasket is hardened, flattened, cracked or perished
  • Scale, corrosion debris or residue has built up on the sealing face
  • A leak reappears at the joint after the appliance is run up to temperature
  • Pressure loss or intermittent leakage traced to the sealed joint

Before you order

  • Confirm your appliance model against the fit list above before ordering
  • Check the data plate on the appliance for the exact model reference
  • Inspect the mating surfaces for pitting, distortion or damage before fitting a new gasket
  • Check how many seals the joint requires so you have enough for the job
