What it is
The Biasi BI1253105 is an NBR O-ring gasket measuring 2.62mm x 22.22mm. It is used as a sealing component in Biasi gas boilers, including the Activ A and Riva Advance HE ranges. The O-ring provides a fluid-tight seal at the joint where it is fitted.
Signs this part needs replacing
- Water weeping or dripping from the joint where the O-ring sits
- Visible flattening, cracking or perishing of the O-ring
- Hardened or brittle rubber that no longer seals
- Scale or debris trapped on the sealing face
- Recurring pressure loss traced to the joint
Before you order
- Confirm your boiler model and GC number against the fitment list
- Check the existing O-ring dimensions (2.62mm x 22.22mm) match
- Inspect the sealing surfaces for damage or corrosion before fitting
- Check whether more than one O-ring is required for the repair
