Contact UsCustom Piston Ring Manufacturing Capabilities
Custom engineered and manufactured piston rings, and seal rings are essential to the successful functionality of any application. They are specifically designed to form a seal between the piston and the cylinder wall. Once the seal is formed, pressurized gases are prevented from escaping.
Precision rings understands custom quality manufacturing. They have been designing and manufacturing custom piston rings for over 70 years and providing the highest quality standards for all their project designs. Whether it’s custom design manufacturing, heat treatment, turning, grinding, or milling, Pri’s experts provide what is needed.
Learn more about Precision ring’s piston ring and seal ring custom design and manufacturing capabilities by contacting the sales team or calling 317-247-4786 for assistance.
Piston Ring and Seal Ring Custom Capabilities
Precision rings is a leading manufacturer and supplier of piston rings, focusing on custom design and fabrication.
Precision rings specializes in piston rings for harsh environments, including extreme temperatures, high pressures, and tight tolerance requirements. The experts can manufacture piston rings from custom prints and provide custom piston ring engineering services designed to the application requirements.
Custom manufactured seal rings provide enhanced sealing capabilities for a broad range of applications. Seal rings are typically used in applications where leakage is critical. Types of seal rings include but are not limited to two-piece and three-piece ring assemblies.
Contracting and Expanding Rings for Power Generation
Precision rings, incorporated has been designing and manufacturing expanding rings and contracting rings used in power generation for decades. Piston rings produced are used in the nozzles of large turbines, sealing different sections or stages, and in gearboxes. Precision rings also manufactures shaft seals for sealing a spinning shaft against a stationary housing. Commonly referred to as contracting rings, these rings seal on the inside diameter.
Precision rings, inc. designs, engineers, and manufactures custom industrial piston rings and seal rings. Piston rings and seals can be manufactured from an existing print or many years of engineering experience can be used to design a custom piston ring solution for the most challenging application.
Custom Eco-Friendly Seal Ring Manufacturing
Proper seals promote an all-around healthier environment. Whether it’s preventing harmful substances such as jet fuel and “heavy” water from nuclear power plants from entering the atmosphere, eco-friendly seal rings provide the needed leakage protection.
