Derek Smith
40mm x 50mm x 8mm U-Cup Hydraulic Seal
Excellent service

Tried the local stores and couldn’t get the seals that I wanted. Most online retailers wanted to sell me hundreds of different sized seals - most would have ended up in the bin.

TotallySeals provided exactly what I needed, delivered quickly and communicated extremely well.

What are Pneumatic Seals?

Pneumatic Seals are specialised seals designed to contain pressurised air or gas within pneumatic systems. Used in applications like cylinders, valves, and actuators, these seals prevent air leaks, maintaining the necessary pressure for smooth, reliable operation. Typically made from materials with low friction and excellent wear resistance, pneumatic seals offer consistent performance across a range of operating conditions.

How do Pneumatic Seals work?

Pneumatic Seals create an air-tight barrier within cylinders and valves, ensuring that pressurised air is contained within the system. As the components move, the seal maintains contact with the cylinder wall, preventing leaks. This containment allows pneumatic systems to operate efficiently by preserving pressure and enabling controlled motion, which is critical for applications that require precise and smooth operation.

What are the benefits of a Pneumatic Seal?

Pneumatic Seals provide a secure, leak-free environment that enhances the efficiency of air-powered systems. They are designed to handle low friction, reducing wear and enabling smooth motion within the pneumatic system. By maintaining pressure, pneumatic seals support consistent performance, reduce energy loss, and help prolong the lifespan of the equipment, making them ideal for use in demanding applications.

How to choose the correct Pneumatic Seal?

Choosing the right Pneumatic Seal depends on factors like the operating pressure, temperature, and the environment in which the equipment operates. Material selection is also essential, as the seal material must be compatible with the system’s operating conditions. Assessing these factors carefully will ensure an effective seal and optimal performance in pneumatic applications.
