What Is a Pneumatic Seal?
A pneumatic seal is a crucial component designed to ensure tight sealing within machinery or equipment parts.
Constructed from flexible materials like rubber or plastic, these seals achieve their sealing effectiveness through the use of compressed air. They are commonly employed in various types of pneumatic equipment, including cylinders, valves, pumps, and motors, where compressed air serves as the operational medium.
Upon application, compressed air exerts pressure around the seal, causing it to expand or compress against the external force. This action allows the seal to snugly fit against the components or structures it is meant to seal, effectively preventing the escape of fluids, be it air or liquid. The continuous application of external pressure ensures that the seal remains effective and leakage is minimized.
