In 1888, inventor Charles Lee Cook founded the C. Lee Cook company. The company was the producer of the first metallic packing used on piston rods for locomotives and steamships.

In 1955, C. Lee Cook became one of the founding companies of Dover Corporation. Fred Durham, a metallurgist who joined C. Lee Cook in 1923 to develop a more durable metal composite and who bought the company in 1928, became the first CEO of Dover Corporation.

Today’s Cook Compression was formed in 2007 from four previously independent operating companies owned by Dover Corporation: C. Lee Cook; Cook Valve (formerly Cook Manley and Compressor Valve Engineering/CVE); Compressor Components Incorporated (CCI), and American Industrial Components.

In 2009, Cook Compression acquired Mechanical Field Services, LP, a provider of repair, maintenance and overhaul services for reciprocating and rotating equipment.

Today, Cook Compression continues the legacy of invention and firsts, and is dedicated to leveraging industry-leading engineering, manufacturing and service to give you the best possible compressor and engine reliability.
