Engineered for demanding hydraulic applications where standard elastomers fall short, our Fluorocarbon 75A Durometer O-Rings deliver exceptional chemical resistance and thermal stability in a single precision-molded seal. Whether you're sealing hydraulic cylinders, pumps, or manifold ports, these rings hold tight where it counts.
Key Features
Material: Fluorocarbon (FKM/Viton®) — superior resistance to petroleum-based hydraulic fluids, synthetic fluids, and aggressive chemicals
Durometer: 75A Shore A — balanced hardness for reliable sealing under dynamic and static hydraulic pressure
Temperature Range: –20°F to +400°F (–29°C to +204°C)
Pressure Rating: Suitable for high-pressure hydraulic systems; use with back-up rings for pressures exceeding 1,500 PSI
AS568 Compatible: Available in standard AS568 dash sizes for direct groove compatibility
Low Compression Set: Maintains seal integrity over extended service intervals
Ideal Applications
Hydraulic cylinders and actuators
Pumps, valves, and manifolds
Mobile and industrial hydraulic systems
High-temperature fluid power circuits
Environments with exposure to fuels, oils, and solvents
Specify your AS568 dash size when ordering. Back-up rings available separately for high-pressure installations.
