Precision Hydraulic Seals
Precision Hydraulic Seals
Servo Valve / Hydraulic Actuator O-Rings
Designed for tight-tolerance hydraulic control circuits, our Servo Valve and Hydraulic Actuator O-Rings deliver micro-inch dimensional accuracy and rapid pressure response. Manufactured from high-modulus NBR, Viton, or HNBR rubber compounds, these seals resist explosive decompression, extrusion under high hydraulic pressure, and fluid degradation.
Key Technical Features
- Tight dimensional tolerances eliminating hydraulic fluid bypass
- High shear and tear resistance under rapid valve cycling
- Extrusion resistant under high differential impulse pressure
- Inspected for micro-surface defects and parting line flashes
Target Applications
- Electro-Hydraulic Servo Valves
- High-Pressure Proportional Hydraulic Valves
- Hydraulic Cylinder Actuator Pistons & Glands
- Precision Fluid Power Manifolds
- Industrial Press & Motion Control Systems
