Precision Rings, Inc. (PRI) has a well-established history of supplying Aircraft Seal Rings to all major aviation companies both public and private. PRI’s Aircraft Seal Rings can be used for all kinds of fuselage and body applications such as the door, landing gear, butterfly valves for de-icing, auxiliary power units, bleed air valves, and chillers. PRI’s design and engineering team will review prints or drawings to help determine the best process to manufacture Aircraft Seal Rings. Precision’s engineering team is also capable of designing Aircraft Seal Rings based on operating conditions including, temperatures, pressures, and environmental conditions. Precision rings, Inc. focuses on nickel based alloys and the super alloys to overcome the temperature swings and operating conditions endured by Aircraft Seal Rings. Precision rings can provide both prototypes and high volume runs. All Aircraft Seal Rings are subjected to our regular quality assurance process as well as applicable FAA, DOD, and MIL specifications as requested.
