Centrally located in the Midwest United States, DTI was established in 1976. Initially specializing in manufacturer of high pressure diesel fuel injection lines, DTI expanded into hydraulics and other pressurized fluid and gas tubing applications, associated end forms, sealing systems, and pipe weldments.

Since that time DTI has continuously grown its capabilities and business. In 2014 DTI expanded its environmentally controlled, Maquoketa, Iowa production facility to 65k square feet.
