What it is
The FSV Ferrule - O-RING is a sealing component supplied by Main for the FSV assembly on the MAIN Severn 4 RS appliance. The ferrule forms the compression seal at the joint while the O-ring provides the secondary face seal. Together they prevent weeping or seepage at the connection point.
Signs this part needs replacing
- Water weeping or a visible drip at the ferrule or O-ring joint
- Damp staining, corrosion or mineral deposits around the fitting
- The O-ring has hardened, flattened or shows cracking when inspected
- The seal leaks after the joint has been disturbed or re-made
Before you order
- Confirm the appliance model matches MAIN Severn 4 RS before ordering
- Inspect the removed ferrule and O-ring so the replacement matches what came off the appliance
- Check the mating face and seating area for damage or debris, as this can cause a new seal to leak
