Glass Filled PTFE Hydraulic Piston Seal Assembly

Engineered for High-Load Hydraulic Performance

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.
