We Make The World’s finest Valve Seat Inserts, and more!

L. E. Jones Company is the world’s largest manufacturer of valve seat inserts for high performance engines. That’s not all we do, but it is the area we pioneered and are most known for since our founding in 1941 – and we do it better than anyone else in the world. This isn’t a claim we make lightly. In a time of corporate diversification and vertical integrations, we have chosen to excel in producing a handful of critical large engine components. We have dozens of patents, geographically deployed R&D and proprietary technology that we harness to assist the biggest and best engine and application makers in the world. Our parts ensure top performance for engines found in trucks, buses, ships, construction and farm equipment, locomotives, gen sets, and aircraft. Made to unbelievably tight tolerances from technologically sophisticated alloys, with near zero parts per million quality performance and production capacity in the tens of millions, L. E. Jones is a world leader. You’ve come to our site for a reason. Use the Learn Module so that you can navigate where you want to get the information you need.

“After 80 years, we know one thing for sure at L. E. Jones: Global Performance is not a happy twist of fate. To be the world’s leading maker of precision valve seats and other parts for non-automotive engine makers takes decades of dedicated research and development for top performing alloys and proprietary production processes, a commitment to globally lean manufacturing with the best people, processes and machines and a fervent belief in deploying ever-advancing technology to ensure absolute perfection in the parts we make… millions of them every year.”
