What it is

The Biasi BI1001105 is a flat gasket with a 1 inch size, used to seal a joint on Biasi gas boilers. It is a service part intended for use during maintenance or repair of the appliance's water or gas-carrying connections. The gasket is listed under Biasi's boiler spares range and supersedes code BG1001105.

Signs this part needs replacing

  • Water weeping or dripping from the joint the gasket seals
  • The gasket is visibly hardened, cracked or perished
  • Scale, corrosion or staining around the joint face
  • The joint has been disturbed during a repair and the old gasket cannot be reused
  • Damp patches or residue tracking from the connection

Before you order

  • Check your boiler model against the fit list above before ordering
  • Confirm the gasket size required at the joint is 1 inch
  • Check the existing part or documentation for the superseded code BG1001105
  • Inspect the joint faces for damage or distortion before refitting
