Pneumatic O-Rings
Pneumatic O-Rings are sealing components specifically designed for air and gas sealing applications in pneumatic systems. They provide reliable sealing performance under low to medium pressure conditions, ensuring system efficiency and reduced air leakage.
Our Pneumatic O-Rings are manufactured for industrial automation, pneumatic actuators, valves, and air-handling equipment where consistent sealing and long service life are required.
What Are Pneumatic O-Rings?
Pneumatic O-Rings are elastomer seals used to prevent air or gas leakage between mating surfaces in pneumatic systems. Unlike hydraulic sealing, pneumatic applications typically operate at lower pressures but require excellent elasticity, low friction, and rapid response.
From an engineering perspective, proper material selection and groove design are critical to achieving reliable sealing performance in pneumatic environments.
Sizes & Specifications
Pneumatic O-Rings are available in standard and custom sizes to match various pneumatic components and sealing grooves.
- AS568 inch sizes
- Metric sizes (ISO / DIN)
- Standard and precision tolerances
- Static and dynamic sealing designs
Recommended Materials for Pneumatic Applications
- NBR (Buna-N) – Excellent air sealing and cost-effective choice
- EPDM – Good resistance to moisture and ozone
- Silicone (VMQ) – Wide temperature range and flexibility
- FKM (Viton® equivalent) – For higher temperature pneumatic systems
- HNBR – Improved mechanical strength and wear resistance
Material choice depends on temperature range, operating speed, lubrication, and environmental exposure.
Hardness & Performance Characteristics
- Standard hardness: 70 Shore A
