Safety equipment manufacturer MSA Safety Inc. will acquire Bacharach Inc. and its affiliated companies from FFL Partners. The two companies inked a definitive agreement before announcing the acquisition, a transaction valued at $337 million.

New Kensington, Pa.-based Bacharach provides gas detection technologies used to detect, measure and analyze leaks of various gases that are commonly found in industrial refrigeration as well as industrial and commercial HVAC settings. According to MSA, the acquisition will expand its gas detection portfolio and allow it to leverage manufacturing expertise into new markets. The detection brands of Pittsburgh-based MSA — General Monitors, Senscient, Sierra Monitor and Bacharach — represent more than 325 combined years of gas detection experience.

MSA’s gas detection manufacturing center of excellence and Bacharach’s headquarters are both located in the greater Pittsburgh area. The transaction is expected to close in early July.
