What it is
The Biasi BI1801107 is an O-ring gasket with a cross-section of 2.62mm and an internal diameter of 25.07mm. It is a sealing component used within Biasi Basica COND and Rinnova Adaptive boiler assemblies to prevent water or gas escape at a joint face. The O-ring is compressed between two 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, flattened or lost its elasticity
- Cracks, nicks or cuts visible on the ring surface
- Persistent pressure loss traced to the sealed joint
- Scale or corrosion deposits built up on the ring
Before you order
- Confirm your appliance model against the fit list above
- Check the existing O-ring dimensions match 2.62mm x 25.07mm
- Inspect the mating surfaces for damage before fitting a new seal
- Consider whether other seals on the same assembly also need replacing
