Shaffer, a subsidiary of NOV Inc., is a manufacturer and distributor of pressure control devices for the petroleum industry. The company's products include blowout preventers, control systems, riser string packages, choke valves, riser tensioners, and drill string compensators.
In 1922, William D. Shaffer founded the Shaffer Tool Works in Brea, California to supply the oilfield industry during the second Santa Fe Springs, California oil boom.[1] The company was incorporated in 1938.[2] Shaffer bought the oil field equipment business of Alco Products in 1962.[3]
In 1968, Shaffer, except its Houston, Texas-based Bayport Fabrication division, was bought by Oakland-based Rucker Corporation for US$2.7 million[4][5] and changed its name to Rucker Shaffer.[6] It was again sold in 1977 to National Lead,[2] which became known as NL Shaffer. In 1979, NL Shaffer purchased Koomey Control Systems. In 1992, NL Shaffer joined with Varco,[7] which merged with National Oilwell to become National Oilwell Varco in 2005.
