Overview

The LG MDS47123608 is an O.E.M. authorized replacement gasket engineered to restore a watertight seal in the water filter housing of compatible LG refrigerators. Over time, the original gasket can degrade from repeated filter changes, water pressure, and normal wear, leading to slow leaks or drips around the filter compartment. This replacement part is manufactured to LG's original specifications, ensuring the correct material composition, thickness, and dimensions for a proper fit without modification.

Installation is a simple process that typically requires no tools — the old gasket is removed from the filter housing and the new one is seated in its place before reinstalling the water filter. The entire procedure takes only a few minutes. As an OEM-authorized component sourced from LG's supply chain and manufactured in South Korea, this gasket provides the reliability and fitment assurance that generic aftermarket seals may not match. Before ordering, it is important to verify that your specific LG refrigerator model is compatible with part number MDS47123608.
