Design Request

Disclaimer: Our capabilities are specific to certain applications.

  • What Pri Manufactures: Custom piston rings for Aerospace, Power Generation, and other advanced technologies.
  • What Pri Doesn't Manufacture: Piston rings for automobiles, tractors, power tools, or steam trains.

I would like Precision rings incorporated to design and manufacture a ring for my application. This is for expanding ring mating dimensions.
