What it is
The Biasi KI1043144 is an O-ring gasket measuring 18.64mm x 3.53mm. It is a circular sealing component used in Biasi gas boilers to seal a joint between mating parts and prevent water or gas leakage. It is listed in the O-rings, washers and gaskets category of Biasi gas boiler spares.
Signs this part needs replacing
- Water weeping or dripping from the joint the O-ring seals
- The O-ring is visibly cracked, split or perished
- The rubber has hardened, flattened or lost its round profile
- Scale or corrosion deposits around the sealing face
- Water staining or residue on nearby components
Before you order
- Confirm your boiler model against the manufacturer's parts list
- Check the old O-ring dimensions and compare them with 18.64mm x 3.53mm
- Check whether the superseded code KG2003151 appears on your existing part
- Inspect the sealing faces for damage before fitting
