Description:
This FTF olive (ferrule) insert is engineered for AN‑10 PTFE (Teflon) hose assemblies. Made from high‑quality aluminium, it creates a reliable, pressure-tight seal by compressing around the Teflon liner when the hose end nut is tightened. Essential for maintaining durability and leak prevention in fuel, oil, or coolant systems — especially when reusing fittings.
