Pneumatic rubber seals are critical components used in pneumatic systems to prevent gas leakage, ensuring system stability and performance. Below is an introduction to related types:
Common Types
O-Rings: With a circular cross-section, O-rings are the most common type of rubber seals, widely used in both static and dynamic sealing applications, such as sealing pipe joints in hydraulic and pneumatic systems. They feature a simple structure, are easy to manufacture and install, maintain good sealing performance under both low and high pressure conditions, and are cost-effective with a variety of material options available.Y-type sealing ring: Available in various materials such as fluororubber and nitrile rubber, widely used in industries like hydraulics, machinery, and pneumatics. Resistant to various petroleum-based oils and has excellent wear resistance. Different rubber types can be selected to meet temperature ranges from -60℃ to +200℃.
V-type sealing ring: An axially acting elastic rubber sealing ring, mainly used for sealing rotating shafts, such as bearing seals in industrial machinery. It can prevent internal grease or oil from leaking out and also prevent external splashing water or dust from entering. It features high-speed rotation performance and strong wear resistance.U-shaped sealing ring: Commonly used for dynamic sealing in hydraulic and pneumatic equipment, such as the reciprocating motion sealing of hydraulic cylinder piston rods. It has strong self-sealing ability, enhances sealing effectiveness through its U-shaped design, withstands high pressure and high-speed movement, and can operate stably at high frequencies.
Commonly used materials
Nitrile rubber (NBR): Suitable for general industrial pneumatic systems, with good oil resistance and wear resistance.
Fluororubber (FKM/Viton): Resistant to high temperatures and chemical corrosion, suitable for high-temperature and special medium pneumatic systems.Silicone Rubber (VMQ): High temperature resistance, excellent electrical insulation properties, suitable for high-temperature pneumatic systems and food-grade applications.
Chloroprene Rubber (CR): Good aging resistance, ozone resistance, and weather resistance, suitable for outdoor environments or pneumatic systems exposed to ozone.
Features
Excellent sealing performance: Effectively prevents gas leakage, ensuring the normal operation of pneumatic systems.
Strong adaptability: Suitable rubber materials and seal types can be selected according to different working environments, adapting to various temperature, pressure, and medium conditions.Flexible Design: Available in various shapes and sizes, and can be customized according to specific requirements to meet the sealing needs of different equipment.
Application Areas
Industrial Manufacturing: Such as in cylinders, pneumatic conveyors, and other equipment, ensuring gas sealing and the normal operation of the equipment.
Aerospace: Used for sealing tight panels, aircraft maintenance doors, cockpit covers, and other parts, where the performance requirements for seals are extremely high.
Electronic Equipment: In some electronic devices that require high-precision control and prevention of gas leakage, such as precision instruments, semiconductor manufacturing equipment, etc., pneumatic rubber seals are also used.
