History

SPX was founded in 1912 in Muskegon, Michigan, as the Piston Ring Company. The company designed and manufactured original equipment components for Detroit’s largest car companies, and quickly earned a reputation for quality products serving the rapidly developing automobile industry.

After acquiring Accuralite Company in 1931, the company changed its name to "Sealed Power Corporation" and also started manufacturing piston rings, pistons and cylinder sleeves for various military applications. By the 1950s, the company had distributors in every state and in more than 40 countries. At the time, Sealed Power products were used as original equipment in more than 80 percent of American-made cars and trucks.
