Dorman's Oil Drain Plugs are coated for high corrosion resistance and long service life, the company says. There are many styles available, including standard, inset gasket, molded gasket, magnetic and pilot point. The oversized, piggyback and rubber expanding plugs eliminate the need to replace the entire pan, helping save time, labor and money. The plugs are designed and constructed to strict engineering quality standards, and are also included with many of Dorman's Engine Oil Pans.
