Enpro Inc

An industrial technology company that makes gaskets, seals, and precision parts for everything from truck brakes to semiconductor manufacturing equipment. Its brands include Garlock, STEMCO, and Technetics, and its customers range from commercial vehicle fleets to chipmakers. The company was spun off from Goodrich Corporation in 2002, but its roots run deep: Garlock, one of its flagship brands, was founded in 1887 by Olin J. Garlock, who invented a better way to seal steam-engine piston rods. Today Enpro also supplies optical coatings and cleaning services for the semiconductor industry through brands like NxEdge and Alluxa.
