About Tramec Sloan
About Tramec Sloan
Tramec Sloan was formed in 2013 when Tramec, LLC acquired Sloan Transportation Products, bringing together companies with a combined history stretching back to 1977. Sloan Transportation Products began as a division of Sloan Valve Company supplying OE-quality air brake and electrical components to the heavy-duty tractor and trailer markets, while Tramec Corp traced its own roots to 1981, when founder Sergio Campanini developed the widely used 31402 hose end repair kit in Iola, Kansas.
Later in 2013, Tramec Sloan acquired Crawford Machine, Inc. (CMI), a brass fitting and hose assembly manufacturer founded in 2001 by the Hessey family, adding in-house brass manufacturing capability to the product lineup. Headquartered in Holland, Michigan, Tramec Sloan now supplies one of the industry's broadest replacement-part catalogs for heavy-duty trucks and trailers, spanning air and electrical delivery components, lift gate cylinders, hose clamps, gladhands, and accessories.
The product range also includes brass fittings, water pumps, oil filler caps and dipsticks, air compressor discharge hoses, and Michelin heavy-duty wiper blades sold to both OEMs and the aftermarket. On ChatMRO, fleet maintenance teams and parts buyers can search Tramec Sloan's catalog by part number or application and route RFQs straight to verified suppliers without digging through separate brand websites.
