Diesel Supply Company, USA (DSC) was established in 1945 and relocated from Joplin, Missouri, to more efficient facilities in Odessa, Texas during July/August of 1994.

DSC was developed for the purpose of supplying the natural gas pipelines with products, primarily replacement parts for the engines and compressors. Manufactured replacement parts are a mainstay for Diesel Supply Company. Moreover, DSC has always been known as “The piston ring company” and is the largest stocking distributor for Kiene Valves in the country.

Diesel Supply’s legendary tool line is still going strong some 60 years later. Customers around the world know they can trust DSC’s quality engineered Piston Ringers, Glaze Busters, Dial Bore Gauges, and Groove Cleaners.

DSC has an inventory of over 1500 gas engine parts as well as a library of over 5000 manufacturing parts prints for many of the wear parts on the Worthington, Clarks, Ingersoll-Rand, and Cooper-Bessemer engines that have been the workhorses of the natural gas industry for many years. DSC also designed and patented cost effective field installed Controlled Rapid Burn (CRB) pre-combustion chambers, check valves, and modified High Flow Fuel Valves for emission reduction low enough to meet any current air quality standards.
