Diesel Locomotive Piston Rings

Since the inception of the diesel-electric locomotive in the 1940s, Kaydon Ring & Seal has designed and produced diesel engine piston rings for the major OEMs and railroads worldwide. EMD, General Electric and Alco medium speed diesel locomotive engines have all relied on Kaydon piston rings for reliable, trouble-free operation.  

Kaydon’s emissions control ring sets help reduce particulate emissions by reducing both initial and long-term oil consumption and have been qualified to meet EPA emissions regulations. Kaydon continues to be the source for innovation in piston ring designs in the face of ever-changing environmental requirements for gas fueled and diesel engines.
