Bostec metal seals are manufactured at our advanced CNC facility in Los Angeles, California. Our high degree of automation insures that Bostec products are competitive with metals seals manufactured anywhere in the world. Being located in Southern California affords Bostec an additional and significant competitive advantage because of the large and highly sophisticated local vendor and labor base that exists due to Southern California being home to the world's largest aerospace companies.


Since it's inception in 1992, Bostec has perfected specialized and proprietary machine tool and holding mechanisms that prevent deformation and allow tight tolerances and absolute concentricity for the manufacture of annular metal seals.
