Glass Filled Nylon Rubber Energizer Hydraulic Piston Seal Assembly
Engineered for demanding hydraulic piston applications, this seal assembly combines a glass filled nylon (GFN) wear ring with a rubber energizer to deliver consistent sealing force, low friction, and exceptional wear resistance across a wide range of operating conditions.
The glass-filled nylon outer element provides superior dimensional stability and extrusion resistance under high-pressure cycling, while the elastomeric energizer maintains continuous radial load against the bore — ensuring a leak-free seal even as the primary element wears over time.
Key Benefits
Maintains consistent sealing pressure throughout service life
Glass-filled nylon resists extrusion, deformation, and chemical attack
Rubber energizer compensates for wear and thermal expansion
Low breakout and running friction for smooth, efficient cylinder operation
Suitable for both static and dynamic piston sealing applications
Compatible with mineral-based hydraulic oils, water glycols, and many synthetic fluids
Typical Applications
Hydraulic cylinders in industrial machinery, mobile equipment, agricultural implements, and construction equipment where reliable double-acting piston sealing is required.
