What TRISEAL CORPORATION does

TRISEAL CORPORATION operates commercially as Amsted Seals, a privately held manufacturer and distributor of heavy-duty wheel-end and precision sealing components. Founded in 1985 and headquartered in the United States, the company is a subsidiary of Amsted Industries, a diversified industrial conglomerate, and serves commercial trucking (primary), rail, automotive, agriculture and construction, recreational vehicle, industrial equipment, and appliance markets globally.

The core product portfolio consists of wheel seals, pinion seals, hub caps and gaskets, axle nuts (sold under the ProLock brand), and wheel-end accessories and tools, marketed primarily under the Triseal product family. Manufacturing leverages proprietary Inno-Spin metal forming technology alongside precision machining, custom seal design, application engineering, problem seal analysis, and in-house testing capabilities. The company supplements hardware sales with engineering services that allow seals to be specified to tight tolerances across multiple industries.

TRISEAL CORPORATION generates revenue through direct B2B hardware sales to commercial vehicle fleets, OEM manufacturers, and industrial customers on a quote-based pricing model with multi-year contracts. Go-to-market is anchored on enterprise field sales, supplemented by a self-service Part Interchange online tool for aftermarket part identification and Wheel-End Training programs for fleet maintenance customers. The company is actively expanding capacity through a new state-of-the-art manufacturing facility in Mexico that is expected to create nearly 150 jobs, reflecting its role within the larger Amsted Industries manufacturing footprint.
