History and Heritage
In 1912, the Piston Ring Company officially opened for business in Muskegon, Michigan. 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 the Accuralite Company in 1931, the company changed its name to “Sealed Power Corporation” and started manufacturing piston rings, pistons and cylinder sleeves for 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.
By 1988, and after a number of strategic acquisitions to further diversify the company into a replacement parts and specialty service tool manufacturer, the company changed its name to SPX Corporation. For the next 10 years, we remained a U.S.-centric automotive component manufacturer with nearly $1 billion in sales.
With more than $2 billion in annual revenue and over 4,400 employees in 16 countries, SPX offers a wide array of highly engineered infrastructure products with strong brands.
