Business Combinations [Abstract]
Acquisitions	Acquisitions In February 2015, we acquired the stock of ATDynamics, Inc. ("ATDynamics"), a privately-held company offering innovative aerodynamic products to the commercial trucking industry. ATDynamics is managed as part of our Stemco division within the Sealing Products segment. ATDynamics, headquartered in Hayward, California, is a leading designer and manufacturer of a suite of aerodynamic products engineered to reduce fuel consumption in the global freight transportation industry. We paid $30.6 million, net of cash acquired, for the business. The acquisition of ATDynamics includes an agreement that could require us to pay additional consideration based on the future gross profit of ATDynamics during the twelve months subsequent to the acquisition. The range of undiscounted amounts we could pay under the contingent consideration agreement is between $0 and $5.0 million. The fair value of the contingent consideration recognized on the acquisition date was $0.5 million, which is included in accrued expenses in the accompanying Consolidated Balance Sheet as of June 30, 2015. Because the assets, liabilities and results of operations for this acquisition are not significant to our consolidated financial position or results of operations, pro forma financial information and additional disclosures are not presented. Subsequent to the second quarter of 2015 (July 1, 2015), we purchased the Veyance North-American air spring business (the "Air Spring Business") for $18.1 million in cash. The Air Spring Business is a manufacturer of air springs that are used in the suspension systems of commercial vehicles. Following the acquisition, it became part of EnPro's Stemco division within the Sealing Products segment. The Air Spring Business manufactures products in its facility in San Luis Potosi, Mexico with a commercial organization in the U.S., Canada and Mexico, and engineering, testing and administrative resources in Fairlawn, Ohio. The addition of the Air Spring Business significantly expands Stemco's presence and scale in the commercial vehicle suspension market.
