All of our Rider Rings & Bull Rings are 100% OEM compatible and are formulated to achieve the best possible results in each application.


The purpose of the rider ring is to protect the cylinder wall from contact by the piston. The rider ring, made of low friction materials like blended Teflon™ or bronze, prolongs piston and liner longevity. Riders and bullrings are manufactured in step-cut, butt cut angle, or solid configurations. Over-sized dimensions are available. Rider rings/bull rings are designed to provide optimal performance in reciprocating compressors. They are suitable for both lubricated and non-lubricated compressors. Worthington Division rider rings/bull rings meet or exceed the original manufacturer’s specifications and are 100 % OEM compatible. Worthington Division provides quality rider rings/ bull rings for compressors manufactured by Worthington, Ingersoll-Rand, Quincy and Gardner-Denver.
