Hydraulic O’rings and seals
Hydraulic O-rings and seals prevent fluid leakage, maintain internal pressure, and block external contaminants from entering hydraulic systems. Because they must withstand extreme pressures, constant movement, and aggressive fluids, choosing the correct seal type and material is critical for avoiding system failure.
- Operating Pressure : High Performance Range
- Application : Industrial & Mobile Systems
About this item
Hydraulic O-rings and seals are critical elastomeric components engineered to contain fluids, maintain system pressure, and prevent external contaminants from entering fluid power systems. They act as a foundational element in industrial machinery, automotive systems, and aerospace engineering.
| Material | Temperature Range | Best Fit Applications & Features |
|---|---|---|
| Nitrile / Buna-N (NBR) | -40°C to 120°C | Standard industry choice. Excellent oil, fuel, and wear resistance. |
| Viton / Fluorocarbon (FKM) | -20°C to 200°C | High-temperature situations. Resists aggressive chemicals and synthetic fluids. |
| Polyurethane (TPU/PU) | -35°C to 100°C | Exceptional mechanical strength. Highest resistance to extrusion and abrasion. |
| Hydrogenated Nitrile (HNBR) | -30°C to 150°C | Enhanced thermal resistance. Fills the gap between standard NBR and Viton. |
