Piston Seals

  • Piston 2

    Pneumatic Piston sealing systems are designed to be as efficient as possible.  Limiting friction on the Cylinder bore is the most important design consideration.

  • Piston 1

    Spring energized seals with cantilever springs can be used as pneumatic Piston seals.  They will require special piston head designs for installation.

  • Piston 5

    Elastomeric energized Piston seals can be utilized in pneumatic applications.

Piston seals or rings are used in Pneumatic cylinder systems.  Machined grooves in the cylinder piston allow the piston ring to seal directly against the cylinder bore.  A wide range of groove configurations and sealing profiles allow Gallagher Engineers to match your Pneumatic sealing application to the optimal sealing system.

Gallagher offers 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.
