What it is

The Biasi BI1475119 is an O-ring gasket measuring 1.78 mm x 6.75 mm. It is a sealing component used within Biasi gas boiler assemblies to prevent fluid and gas leaks at the joint it sits in. It is listed by the manufacturer as a boiler spare part.

Signs this part needs replacing

  • Water or gas weeping from the joint the O-ring seals
  • The O-ring is flattened, hardened or no longer sits proud of its groove
  • Visible cracking, splitting or perishing of the rubber
  • Scale or corrosion deposits on the O-ring or its seating
  • A joint that continues to leak after being re-tightened

Before you order

  • Confirm the O-ring dimensions (1.78 mm x 6.75 mm) match the one being removed
  • Check your boiler model against the compatibility list above
  • Inspect the seating groove for damage, scale or corrosion before fitting
  • Confirm how many O-rings the joint requires before ordering
