PTFE GSF Piston Seals Glyd Rings

Hydraulic Piston Seals-GSF Glyd Rings

Piston seals maintain sealing contact between the piston and the cylinder bore. Differential pressures acting on the piston to extend or retract the piston rod can exceed 400 bar (5,800 psi). 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.
