The Glass Filled PTFE Hydraulic Piston Seal Assembly delivers exceptional sealing integrity in demanding hydraulic cylinder applications. Manufactured from glass fiber-reinforced PTFE, this piston seal assembly offers superior dimensional stability, reduced cold flow, and outstanding resistance to extrusion — even under sustained high-pressure cycling.
Key Benefits
Enhanced Wear Resistance — Glass fiber reinforcement extends service life vs. virgin PTFE
Low Friction Operation — PTFE's inherent lubricity minimizes stick-slip and breakout force
Broad Chemical Compatibility — Resistant to hydraulic oils, water-glycol fluids, phosphate esters, and most industrial hydraulic media
Wide Temperature Range — -65°F to +450°F (-54°C to +232°C)
Extrusion Resistance — Glass fill reduces material creep and extrusion into clearance gaps
Typical Applications
Industrial hydraulic cylinders
Mobile equipment and heavy machinery
Press and forming equipment
Injection molding and die casting machinery
Aerospace and defense hydraulic actuators
Designed as a complete assembly for drop-in installation, available in standard bore sizes and can be configured for custom dimensions.
