For nearly 50 years, the name Mr. Gasket® has been associated with the race-winning performance and efficiency. The history of the company's development is a real American success story. Mr. Gasket was founded by Joseph F. Hrudka in late 1964. Using his drag race car, the 1957 Chevy, as a test automobile, he understood the need and decided to create a vast line of engine gaskets and fasteners that would withstand high engine pressures, temperatures, and other stresses experienced by the cars used for drag racing. There have been many days and nights since that fateful moment, and today, all Mr. Gasket products, proven to work effectively on racing circuits around the world, have achieved both a legendary status in motorsports and trusted reputation in the marketplace.
