What it is
The Biasi KI1003114 is an O-ring gasket measuring 3mm x 17mm. It is a sealing component used on Biasi gas boilers, sitting between mating faces to prevent water or gas leakage at the joint. The O-ring profile compresses into the joint to form a tight seal once the connection is tightened.
Signs this part needs replacing
- Water weeping or traces of scale at the joint the gasket seals
- The O-ring feels hard, flattened or brittle rather than pliable
- Visible splits, cuts or cracking on the ring surface
- Persistent drips after the joint has been re-tightened
- Discolouration or compression set where the ring has taken the shape of the groove
Before you order
- Confirm the dimensions of the existing O-ring, 3mm x 17mm, against the part you are removing
- Check your boiler model against the fitment list above before ordering
- Inspect the mating faces and groove for corrosion, scoring or old seal residue
- Renew the O-ring whenever the joint it seals is disturbed
