What it is

The Biasi BI1262113 is an O-ring gasket with a cross-section of 2.62mm and an internal dimension of 9.92mm. It is used as a sealing component within Biasi gas boiler assemblies, where it seats between mating surfaces to prevent water or gas escape. It is supplied as a single sealing ring.

Signs this part needs replacing

Visible water or gas weeping at the joint the ring seals
The ring has hardened, cracked or become brittle with heat ageing
The ring is flattened or deformed and no longer sits proud of its groove
Traces of corrosion or scale in the sealing groove
A joint that continues to seep after the assembly has been re-tightened

Before you order

Confirm the cross-section and internal dimension match the ring removed from the appliance
Check the appliance model against the manufacturer's parts list to confirm the part number
Inspect the sealing groove and mating faces for damage before fitting a new ring
