Hydraulic Cast Iron Piston Rings and Seals

AD Piston ring offers piston rings and seals for OEM manufacturers of hydraulics and hydraulic repair shops. Piston rings and seals are used in hydraulic cylinders for fluid sealing. The piston rings and seals are internal to the cylinder head and seal against the cylinder bore, preventing fluid from flowing across the cylinder head. This allows pressure build up on one side of the piston, making the cylinder extend or retract. Since 1955 AD Piston Ring has manufactured quality piston rings for the hydraulic industry. Our staff has over 70 years of combined experience in designing and manufacturing piston rings and seals for hydraulic applications.

Piston rings are most frequently used today in sealing medium and high pressures for hydraulic equipment such as machine tools of all types, road and mobile machinery of all types, thousand ton presses, dams, etc. These piston rings for hydraulic applications are made from alloys of bronze and cast iron, depending entirely on the type of machinery, pressures, operating conditions, temperature reached, etc.

We have developed our proprietary Shurseal piston ring product for piston ring manufacturing allowing us to produce piston rings and seals for air compressors, die cast machines, garbage trucks, cylinders on road graders, shock absorbers, hydrostatic transmissions, turbo chargers, and steam turbines with the least amount of leakage.

These accomplishments allow us to offer you unsurpassed service in quality, price and delivery.
