We have been in business since 1936 (Wow...that is a really long time!). Headquartered in Spartanburg, South Carolina, with tanker parts and hose distribution facilities in Cincinnati, Chicago, Los Angeles and Commerce City, CO, Littlejohn has America’s largest tank trailer parts and hose inventory in stock. “We love tank trailer parts & hose” From Betts manholes to Civacon overfill; from Dixon valves to Kanaflex hose - if it is a tank trailer part or hose, we have it in stock at our 5 locations. Why are we so passionate about Tanker Parts? The answer is easy. We believe that by supplying parts and hose to our customers, we keep tank trailers running, providing critical products that keep America moving. Petroleum, chemical, dry bulk and food grade tankers all support and help others.
