Fluid power seals used in pneumatic cylinder systems represent some of the most overlooked, yet vital components in its construction and operation. Without these rubber seals – or if using inferior seals – the friction and leakage created by the process of using a pneumatic cylinder application could cause the equipment to catastrophically fail, risking severe damage and injury, and requiring great cost to repair or replace.

Gallagher Fluid Seals' partner, Precision Associates, has innovated to create our own unique and patented compounds for rubber pneumatic piston seals—suitable for all sorts of pneumatic applications. These U-Cups are designed to function with vastly lower breakaway and operating friction than any similar product in the marketplace.

What Are Pneumatic Cylinder Systems?

Utilizing compressed gas as a power source, mechanical pneumatic cylinders produce a reciprocating linear motion force. Like hydraulic cylinders, this force drives a piston in the required direction and the piston is usually a disc or cylinder. The corresponding rod transfers the force it creates to the object requiring movement. Engineers often choose pneumatic cylinders over other methods due to pneumatics being quieter, producing less waste, and requiring significantly less amounts of space for fluid storage.

Pneumatic cylinders can vary in configuration, but generally fit into one of three specific categories:
