Custom Piston Ring Materials

Precision rings, Inc. uses a variety of materials when manufacturing custom piston rings and seal rings. These can include polymers, as well as the "Super alloys", materials of high Nickel or Cobalt content. Polymers have good sealing characteristics for lower temperature applications. The "super alloys" have excellent properties for harsher environments. These environments include high heat, cryogenic temperatures, corrosive fluids and high pressures. Precision rings incorporated manufactures from castings, forgings, bars and wire. The material form is often determined by the application. It is also important that the ring material is compatible with the mating materials in a system. The correct material allows the ring to be the sacrificial part in a properly engineered system. Please let Precision Rings recommend a material for your next application.
