Mr. Gasket Engine Oil Drain Plug Assemblies: Racing Heritage Meets Everyday Engine Protection

When it comes to the small components that make a big difference in engine longevity, Mr. Gasket has earned its place in the garage of serious enthusiasts and everyday drivers alike. Engine oil drain plug assemblies may seem like a minor detail, but the right plug — designed with performance engineering principles — can actively protect your engine during every oil change cycle.

Mr. Gasket's roots run deep in American motorsports. Drag racer Joe Hrudka founded the company using his own '57 Chevy as a rolling test bed, and quickly built a reputation at Cleveland-area tracks by producing sealing solutions that could withstand the punishing temperatures and pressures of competition engines. That same no-compromise philosophy carries through to every drain plug assembly the brand produces today.

Magnetic Technology That Works Between Oil Changes

The standout feature in Mr. Gasket's oil drain plug lineup is its rare earth magnetic drain plug (part #15). Unlike a standard plug that simply seals the drain hole, this assembly uses a built-in magnet to continuously accumulate ferrous metal particles suspended in your engine oil. These microscopic shavings — generated by normal wear in the cylinder walls, crankshaft, and other moving components — can circulate through the oiling system and gradually score rod bearings and main bearings. By trapping them at the drain plug, Mr. Gasket's assembly adds a passive layer of protection that works every mile between oil changes.

The plug is precision-machined with 1/2"-20 right-hand threads and features a 3/4" hex head for easy installation and removal. It includes a rubber seal washer for a leak-free fit and is finished in polished chrome — a nod to Mr. Gasket's tradition of combining function with under-hood appearance. The plug is engineered to fit aftermarket oil pans with 1/2"-20 SAE threads, with broad application coverage spanning classic American V8s from Chevrolet, Chrysler, Ford, Pontiac, Oldsmobile, and Buick.

A Brand Now Backed by Holley Performance

Now an important part of the Holley Performance family, Mr. Gasket continues to develop products that serve both race cars and muscle cars. The brand's oil drain plug assemblies reflect that dual mission: engineered with the precision demanded on the track, but practical and accessible for weekend builds and routine maintenance alike. For anyone who takes engine health seriously — whether on a restored classic or a dedicated strip car — choosing a Mr. Gasket magnetic drain plug assembly is one of the simplest upgrades you can make at oil change time.
