What it is

The Worcester Bosch 87161061450 is an air box seal measuring 80mm, used on Worcester Danesmoor FS 18/25 oil-fired appliances. It sits at the air box joint, sealing the mating faces so that combustion air is drawn through the intended path rather than leaking past the casing. A sound seal here keeps the burner's air supply consistent and prevents flue gases or odours escaping into the surrounding space.

Signs this part needs replacing

  • Visible cracking, flattening or hardening of the seal material
  • Oil or soot staining around the air box joint
  • Combustion readings drifting or the burner running with an unstable flame
  • Whistling or hissing from the air box area while the burner is running
  • The seal no longer sitting proud of its groove or failing to compress on reassembly

Before you order

  • Confirm the appliance model and, where available, the GC number against the compatibility list before ordering
  • Check the existing seal dimensions and profile match the 80mm air box seal listed here
  • Inspect adjacent gaskets and seals on the air box while access is open, as they may need replacing at the same time
  • Work on oil-fired combustion components should be carried out by a competent engineer
