Piston Seals

  • buffer seals1

    Piston sealing systems can be designed with opposite facing, single direction piston seals.  A piston bearing or wear ring will also be utilized for piston sealing stability.

  • Piston 1

    Spring energized piston seals are a high performing sealing solution for specific piston sealing applications.

  • Piston 4

    Elastomeric energized PTFE piston seals offer tremendous bi-directional sealing performance in hydraulic piston sealing applications.

Case Study Icon FAPiston seals are used in hydraulic 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 hydraulic sealing application with the optimal sealing system.

Gallagher offers the highest performing urethane materials for your hydraulic application.  New advances in hydrolysis resistant urethanes assist in solving one of the most common hydraulic sealing application problems.

Case Study Icon FAHydraulic fluid leakage continues to be an important regulatory issue.  Advances in more environmentally friendly hydraulic fluid is causing some material compatibility issues with traditional cylinder seals.  Ensure that the seals in any hydraulic system are optimized for the hydraulic fluids of the future.
