Owned by Federal Mogul, the Fel-Pro brand offers innovative materials, new technologies, and a relentless focus on sealing solutions for real-world repair conditions.

Fel-Pro is committed to quality U.S.-based engineering and manufacturing. At Fel-Pro headquarters in Skokie, more than 1,300 employees produce over 325,000 gaskets, seals, and other products and ship more than 120,000 complete sealing repair sets daily. Plus, every part that goes into a Fel-Pro box is validated and approved by a Fel-Pro engineer to ensure each gasket has been designed and manufactured specifically for the corresponding repair.

In 1918, Hugo Herz and Albert Mecklenburger established Felt Products Manufacturing Company, producing felt seals for the Ford Model T. Five years later, Felt Products purchased a new manufacturing facility and expanded to gasket sets, oil seals, metallic gaskets, and cork and leather material. Soon after, the company’s name was changed to Fel-Pro to match their expanded selection. By the 1970s, their now-iconic blue gasket materials and Blue Stripe design did its job to differentiate the Fel-Pro brand from the competition. In 1998, Federal-Mogul acquired Fel-Pro. Today, Fel-Pro continues their proud American story by providing premium products that easily address the tough demands of the sealing repair environment.

In the real world, nothing is perfect—including gasket sealing surfaces. And Fel-Pro engineers know that and focus on the real-world conditions facing technicians and other customers. The company’s highly specialized gasket materials and problem-solving designs help each customer achieve a long-lasting seal they can rely on. That’s why Fel-Pro has become a leading, chosen brand in an era of lighter-weight, higher-output, and harder-to-seal engines.

Fel-Pro was one of the first companies to sell complete gasket sets to simplify and speed repair for technicians and DIYers.
