Tramec is built upon a deep history of U.S. manufacturing, product expertise, and great service to provide exceptional value to our customers and industries.
The story began in 1981 with Sergio Campanini founding Tramec Corp in Iola, Kansas. Sergio created the famous 31402 hose end repair kit which was further developed into a full line of hose assemblies. Over the years, Tramec grew through product innovation and a series of acquisitions that have merged rich company histories.
Today, Tramec is a family of companies providing a broad variety of components and assemblies for the commercial vehicle, heavy equipment, air handling, fluid control, automotive, and construction markets.
In 1977 Sloan Transportation Products was formed as a division of the Sloan Valve Company. Sloan Transportation became known as a strong aftermarket provider of OE quality air brake and electrical components for the heavy-duty tractor and trailer markets.
Looking to expand product lines, leadership and facilities, Tramec, LLC acquired Sloan Transportation Products in May 2013 to form Tramec Sloan. This Holland, Michigan location now serves as the company’s primary distribution center.
Founded in 2001 by the Hessey family, CMI got started by producing hose assemblies and bulkhead fittings. They quickly expanded their capabilities and product line, manufacturing over 40 styles of brass fittings.
In November 2013, CMI was acquired by Tramec Sloan to bring brass manufacturing expertise to our product lineup. Located in Galion, Ohio, this facility processes over 9 million lbs of brass each year and we continue to invest in new technologies.
What began in a garage by Louis E. Eklund, Jr. as a start-up in 1963 soon grew into a company built on a solid reputation for producing high-quality truck & trailer products.
In 2018, Fleet Engineers was acquired by Tramec and continues to design and manufacture value-added product solutions for Spray Control, Door Systems, Cargo Control, and more. The Muskegon, Michigan campus of four buildings totals over 300,000 square feet of manufacturing and warehouse space.
A leading manufacturer of the only hydraulic cargo bars for the trucking and transportation industries started in 1994 as a solution to cargo bars that fall while in transit.
In 2016, Fleet Engineers purchased the Charlotte, North Carolina-based company and moved headquarters to Muskegon, Michigan. Save-A-Load® cargo bars became an integral offering Fleet Engineers' Cargo Control product line.
Founded in 1956 as a small tool and die shop, Penz has grown to be a leader in the truck & trailer and container & chassis industries. Founder Wally Penzenik understood the importance of using quality materials and experienced workers to manufacture products at competitive prices.
At the end of 2021, Penz Products joined the Tramec family and continues operations in Mishawaka, Indiana.
