What it is

The Biasi KI1042118 is an O-ring gasket with a 2.62 mm cross-section, used to seal a joint on Biasi gas boilers. It is fitted to appliances in the Basica COND and Rinnova Adaptive families. The O-ring provides a compression seal at the point where it is installed, preventing water or gas leakage from the joint.

Signs this part needs replacing

  • Weeping or dripping at the joint the O-ring seals
  • Visible flattening, hardening or cracking of the O-ring
  • Scale, debris or corrosion deposits on the sealing face
  • Damp staining or water marks around the joint
  • Loss of system pressure traced to the sealed connection

Before you order

  • Confirm your appliance model and GC number against the data badge before ordering
  • Compare the dimensions of the old O-ring with the sizes listed here
  • Check how many O-rings the joint requires, as more than one may be needed
  • Inspect the sealing faces for damage before refitting
