What it is
The Biasi BI1453103 is an O-ring gasket measuring 2.62mm x 18.72mm. It is a sealing component used within Biasi Advance boiler appliances to prevent water or gas leakage at a joint face. The O-ring compresses between mating surfaces to form a fluid-tight seal.
Signs this part needs replacing
- Visible water weeping or damp staining around the joint the O-ring seals
- The O-ring has hardened, cracked or perished with age
- Flattened or deformed profile where the ring no longer sits proud of its groove
- Scale or debris build-up on the ring surface preventing a clean seal
- Repeated pressure loss traced to the sealed joint
Before you order
- Confirm your appliance model against the fit list above
- Check the existing O-ring dimensions match 2.62mm x 18.72mm
- Inspect the sealing groove and mating faces for damage or corrosion before fitting
- Confirm how many O-rings are required for the joint being worked on
