no-mess oil pan drain plug, 1/2 - 20 - patented

This engine oil pan drain plug is a No-Mess model. Features a 12-20 size thread and has a gold iridite finish. The No-Mess engine oil drain plug has a unique, patented, rubber extension which acts as a sealing 'cork' when changing engine oil. As the drain plug is unscrewed and loosened, the cork seals the threaded drain hole, reducing mess and contact with hot oil. A firm tug releases the oil when desired. This drain plug minimizes the chance of a plug being dropped. U.S. Patent 5,547,042. Sold individually. Backed by a limited 30 day factory warranty.
