Choosing the wrong seal type can lead to performance failures and higher maintenance costs. I\u2019ve seen systems shut down simply because a hydraulic seal was used where a pneumatic one was needed\u2014or vice versa.<\/p>\n

Hydraulic seals are built for high-pressure fluid systems, while pneumatic seals are ideal for low-pressure air systems. This article helps you choose the right one based on pressure, material, and application.<\/p>\n

What is the difference between hydraulic and pneumatic seals?<\/h2>\n

While both prevent leaks and contain pressure, they\u2019re designed for different types of systems.<\/p>\n
