Rod seals, or rings, are used in pneumatic cylinder systems to prevent air from escaping the cylinder. Machined grooves in the cylinder housing allow the rod ring to seal directly against the piston shaft.  A wide range of groove configurations and sealing profiles allow us to match your pneumatic sealing application to the optimal sealing system.

We offer the highest performing urethane and PTFE materials for your pneumatic application.  Pneumatic rod seals are designed to limit friction as much as possible to maximize the efficiency of the pneumatic system. 

Pneumatic technology has seen tremendous increases over the past decade, especially in Europe.  New sealing materials and profiles are allowing pneumatic sealing systems to provide levels of efficiency and energy not thought possible historically.
