Over 50 years ago, Joe Moriarty invented the Gapless Piston Ring. Today, Competition, Innovation and Efficiency are the DNA of Total Seal Piston Rings. We utilize racing to develop and prove out ring sealing technologies that apply to engine or compressor. If it takes a piston, we can build a better ring for it.

That spirit began with our founder, Joe Moriarty, and it carries on today.
