Magnum Gaskets Brand Enters Automotive Aftermarket

Established American gasket manufacturer brings Magnum brand directly to the aftermarket.
BANNOCKBURN, Ill. – Magnum Gaskets has entered the automotive aftermarket with a line of American-made, premium-quality gasket sets for cars and light trucks. For nearly 20 years, Magnum’s parent company, Modern Silicone Technologies Inc. (MSI), has been a premier supplier of high-tech molded rubber, plastic and metal gaskets to major aftermarket brands and OE service.

The MSI triangle logo on gaskets is a familiar symbol of quality to thousands of professional technicians and do-it-yourselfers, said Alex Grunfeld, vice president at Magnum Automotive Group. “Our gaskets are already installed on millions of vehicles on the road in North America,” Grunfeld said. “That same quality and reliability can now be found under the Magnum Gaskets brand.”

Magnum offers the industry’s most sophisticated molded gasket designs for late model domestic and foreign vehicles, as well as premium-quality conventional gaskets for popular cars and trucks dating back to the muscle car era, the company says.

The Magnum line includes Magnum MaxDry STL intake manifold gaskets, featuring chemical-resistant, ultra-premium synthetic rubber sealing surfaces, precision molded to aluminized steel carriers. Available for popular applications, such as GM 3.1L, 3.4L, 3.8L, 4.3L, 5.0L, and 5.7L engines, Magnum MaxDry STL gaskets carry an exclusive limited lifetime warranty.

“Magnum MaxDry STL gaskets are just one example of the cutting-edge technology and world-class quality that installers and resellers can expect from Magnum Gaskets,” Grunfeld said.

More than 90 percent of Magnum products are designed, manufactured and packaged in the U.S. The complete Magnum Gasket line covers more than 80 percent of sales in manifold, valve cover and oil pan gasket categories for domestic and import cars and light trucks at very competitive prices, the company says.
