At Hastings Manufacturing, we’ve mastered the engineering and craftsmanship of piston rings. And while others are focused on doing it all, we put our all into one thing. We don’t manufacture other engine components for a reason—it would only take our attention away from what we do best. Decade after decade, we’ve refined and advanced piston ring, compression ring, and vented oil ring design to enhance engine performance, efficiency, and economy. The result is 25,000 SKUs, each made with the highest tolerances and highest quality materials in the industry.
