Precision Rings, Inc. (PRI) has a long history of creating Aerospace Seal Rings. PRI typically focuses on the propulsion systems and body applications, but has created seal solutions for machine guns and experimental weapons as well. Precision’s Seal Rings separate themselves from the competition in the "hot section". PRI’s knowledge allows the best Seal Ring to be created for exhaust or mating needs in this high temperature area. PRI engineers can review prints or drawings to help determine the best solution or lend design expertise to difficult sealing problems or underperforming existing seal designs. Precision excels at finishing design problems in a quick timeframe (7-10 business days from inception of project to the finished design in hand). PRI specializes in the use of super alloys and the manipulation of their properties to solve Seal Ring issues. All Aerospace Seal Rings are subjected to rigorous quality assurance process as well as applicable FAA, DOD, and MIL specifications as requested.
