Metric Pneumatic Seals

A pneumatic seal is a sealing component designed to contain compressed air and prevent leakage within pneumatic cylinders and systems. Pneumatic cylinder seals are commonly installed within cylinders to create an effective seal between moving components, allowing controlled movement and pressure retention during operation. Pneumatic piston seals specifically seal around the piston inside the cylinder bore, helping maintain consistent air pressure and efficient system performance. Metric pneumatic seals are manufactured to metric sizing standards and are designed to provide reliable sealing, low friction and long lasting durability in high-cycle pneumatic applications.

There are several types of pneumatic seals available depending on the application, cylinder design and operating conditions. Common options include pneumatic piston seals, rod seals, buffer seals and compact pneumatic sealing profiles designed for low pressure compressed air systems. Swan Seals supplies metric pneumatic seals manufactured from high-performance materials that provide excellent wear resistance, flexibility and low-friction operation. Different pneumatic cylinder seal profiles are available to suit varying speeds, pressures and motion requirements, ensuring efficient sealing performance across industrial and automation applications.

Pneumatic seals are widely used across manufacturing, automation, packaging, material handling and engineering industries where compressed air systems are used for movement and control. Pneumatic cylinder seals are commonly installed in automated machinery, conveyors, robotics, production equipment and industrial actuators to maintain air pressure and ensure smooth cylinder operation. Pneumatic wiper seals help improve efficiency, reduce air loss and minimise maintenance requirements in high-cycle pneumatic systems. Their low-friction characteristics also support faster movement speeds and reliable operation in demanding industrial environments.

Choosing the correct pneumatic seal depends on factors including operating pressure, speed, temperature, cylinder design and application type. Selecting the appropriate pneumatic piston seal profile and material is essential for achieving effective sealing performance and long service life. Low-friction pneumatic cylinder seals are often preferred for high-speed automation systems, while durable wear-resistant materials are beneficial in demanding industrial environments. It is also important to ensure compatibility with the cylinder dimensions and compressed air system requirements to maintain efficient operation and minimise leakage. Swan Seals offers a comprehensive range of metric pneumatic seals and pneumatic cylinder seals suitable for industrial and engineering applications.
