What it is
A Biasi O-ring gasket measuring 2.7mm in cross-section by 13.6mm internal diameter. It is a sealing component used in Biasi gas boilers, including the Garda, Parva and RIVA Compact ranges, where it forms a watertight or gas-tight joint between mating parts. The gasket is supplied under Biasi part number BI1011117.
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 with age
- Cracking, splitting or surface perishing on the rubber
- A joint that has been disturbed during servicing and will not seal again
- Persistent pressure loss traced to a joint carrying this O-ring
Before you order
- Measure the old O-ring across its cross-section and internal diameter to confirm 2.7mm x 13.6mm
- Check the boiler model and GC number against the manufacturer's parts list for your appliance
- Confirm how many O-rings the joint requires before ordering
- Inspect the mating faces for corrosion or damage that could prevent a seal
