Business Combinations [Abstract]
Acquisitions	Acquisitions On May 1, 2017, the Company acquired 100% of the shares of Hy-Pro Corporation (Hy-Pro). Hy-Pro designs and manufactures filtration systems and replacement filters for stationary hydraulic and industrial lubrication applications. Hy-Pro has manufacturing locations in Anderson, Indiana and Vancouver, Washington. Total consideration for the transaction was $22.7 million. The purchase price allocation is preliminary pending the outcome of the final valuation of the net assets acquired. On August 31, 2016, the Company acquired the net assets of Industrias Partmo S.A. (Partmo) in Colombia. Partmo is a leading manufacturer of replacement air, lube and fuel filters in Colombia for medium and heavy duty engines. The total consideration for the transaction was $12.1 million. For the two acquisitions that occurred in fiscal 2017, the Company acquired $19.5 million of net tangible assets, $8.6 million of intangible assets that had estimated useful lives ranging from seven to twenty years at the time of acquisition and $6.7 million of goodwill. On August 31, 2015, the Company acquired 100% of the shares of Engineered Products Company (EPC), a leading designer and manufacturer of indicators, gauges, switches and sensors for engine air and liquid filtration systems. On June 30, 2015, the Company acquired a majority stake in IFIL USA, a manufacturer of pleated bag filters for industrial dust collection. On September 30, 2014, the Company acquired 100% of the voting interest of Northern Technical, L.L.C. (Northern Technical), a manufacturer of gas turbine inlet air filtration systems and replacement filters. During fiscal 2017, the Company reached a $6.8 million favorable settlement of claims associated with amounts held in an escrow account that had been established in connection with the Company’s acquisition of Northern Technical. Because this settlement was related to claims associated with general representations and warranties and occurred subsequent to one year after the closing of the acquisition, the Company recorded the impact of the $6.8 million settlement as a component of other income, net in its Consolidated Statements of Operations. Pro forma financial information for these acquisitions have not been presented because they are not material to the Company's consolidated results of operations.
