PISTON SEALMADE IN CHINA
Piston 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.
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.
Hydraulic 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.
The pressure acting on the piston seal increases contact forces between the piston seal and cylinder surface. Therefore, the surface properties of the sealing surfaces are critical to proper seal performance
