Industrial applications that include reciprocating and rotary motions require the use of pneumatic cylinders and valves. These cylinders/ valves need specialized pneumatic seals in order to function properly. Known for considerably lower friction than rubber and higher durability, these seals are used across various commercial applications. Certain composite seals (made of two or more different materials) are also used as pneumatic seals.
Based on the type of application, you can pick the most suitable pneumatic seals from the following categories (based on the sealing orientation):
- Internal (rod seal)
- External (piston seal)
- Symmetrical seal
- Axial seal
What are the distinct features of pneumatic seals?
Utilized in various industrial applications, pneumatic seals comprise certain distinct features:
- These seals are helpful in enhancing the operational value of air-actuated cylinders and valves that often involve high speed
- Pneumatic seals are essential for maintaining the desired pressure level in cylinders and valves by restricting the flow of air or gases
- These seals have impeccably low friction and they are highly durable in nature
- They require the minimum amount of lubrication for tight sealing when exposed to air
- The typical pressure range of pneumatic seal is 1 to 150 pound-force per square inch (psi) (about 6.89 to 1,034.2 kilopascals)
- Pneumatic seals are wear resistant
- These seals have high temperature tolerance range
- They are resistant to water and other non-hazardous liquids
- These seals have extremely low friction
- They have secure sealing characteristics and higher speeds of operation
