This is a sealing ring designed to prevent coolant leakage at the radiator drain point, providing a watertight seal when the drain plug is fitted. The ring compresses against the drain port to prevent seepage, which if left unchecked can result in coolant loss, overheating, and potential engine damage. Replacing this seal whenever the radiator is drained is standard practice to maintain an effective seal. Key Features Sealing ring profile matched to the radiator drain plug seat geometry Should be replaced rather than reused, as compression sets the ring and reduces sealing effectiveness on reinstallation Supplied as an OEM-specification component to ensure correct fit at the drain port Inspect the drain plug threads and surrounding plastic or alloy housing for damage when replacing this seal Vehicle Fitment This sealing ring is listed under general fixings and is applicable across all Land Rover vehicles as a universal radiator drain sealing ring (SKU: 213959).
