AOP logoAbout AOP
AOP Industries began operations in 1972 as Oilfield Services Inc in South Oklahoma City, OK. Owned and operated by a local businessman, the initial model for the facility was that of a typical wellhead service organization. In 1977 the company’s name was changed to American Oilfield Products, Inc. The company began manufacturing API 6A and 6D gate valves in 1988, and shortly thereafter began producing the current choke line. Floating ball valves were added to the product line in 1995. Future expansion allowed American Oilfield Products, Inc to included API 6A and 6D ball valves, 6D Swing Check Valves, threaded Check Valves and Needle Valves. The company made an official name change in 1997 to AOP Industries. With expansion in mind, the company purchased a twelve acre site in Moore, OK and in 1998 constructed a 60,000 sq. ft, building. The company relocated from its South Oklahoma City location to the newly constructed facility in Moore, OK in 1998. AOP Industries products are distributed through Regional Representatives and Stocking Distributors both domestically and internationally.
