Gold Plug manufactures Magnetic Sump Drain Plugs of the highest quality. Constructed from a 303 Stainless Steel body that houses the strongest, highest temperature, N45SH Neodymium magnet available. The magnet is secured in place with a proprietary 2 step process and will never come out. Advancements in technology and materials means Gold Plug is continually evolving and at the forefront of technology. The strong Neodymium magnet collects any swarf or wear particles missed by the oil filter, these particles are abrasive and potentially damaging to the engine. The magnet will hold any collected metal firmly, unaffected by temperature variation until the oil is changed. Magnetic sump plugs are a proven product and even used by some manufacturers as standard, examples are available on the market today however few match the quality of Gold Plug and those that do are very expensive.
