Precision Rings, Inc. (PRI) has created Nuclear Seal Rings for pressurized water reactors for use in combustion Engineering. Precision Rings uses a diverse group of stainless steels to solve the many issues that come with sealing hazardous liquids and gases used in the nuclear propulsion system. Manufacturing of the Seal Rings is done in a segregated area and all pieces are kept clean room compliant. All material used in the production of Nuclear Seal Rings is documented with the USA as the country of origin.
