What it is

The Biasi KI1043114 is an o-ring gasket with a 17.04mm bore and 3.53mm cross-section, used to seal a joint within the water-carrying or gas-carrying circuit of Biasi gas boilers. It is a small consumable seal fitted between mating components, and its dimensions are critical to a correct, leak-free joint. The part supersedes code KG2003143.

Signs this part needs replacing

  • Visible cracking, flattening or hardening of the o-ring
  • Weeping or dripping at the joint the o-ring seals
  • Traces of water staining or scale around the sealing face
  • The o-ring is missing, split or deformed after the joint has been disturbed
  • Persistent pressure loss traced to the sealed connection

Before you order

  • Confirm the o-ring dimensions required are 17.04mm x 3.53mm, as fitment depends on exact sizing
  • Check the boiler model and, where applicable, the GC number against the fitment list above
  • Inspect the sealing faces for scoring or corrosion, as a damaged face will not seal with a new o-ring alone
  • Confirm the superseded code KG2003143 does not already appear on your existing part
