For over 60 years, Stein Seal Company has been a leading provider of custom designed seals and precision components for use in a wide variety of aerospace, marine and industrial applications.

As a privately owned company, we have remained focused on our long-term growth strategy regardless of economic and market fluctuations. With over 400 employees and manufacturing facilities strategically located both inside and out of the United States, Stein Seal, along with its affiliated companies, is ideally positioned to provide design, development, sales and service worldwide.

Stein Seal's expertise lies in the design, testing and manufacture of seals and precision components for the demanding and critical applications in military and commercial aircraft engines, power generation equipment, pumps, compressors, centrifuges, and both the military and commercial marine industry. Surpassing our customers' expectations by setting the highest standards for design proficiency and originality, constantly investigating new materials and processes, and refining our ability to manufacture to rigorous tolerances have made us the premier supplier of seals and specialty machined components.
