Engineered for demanding hydraulic cylinder applications, this piston seal assembly combines a glass-filled nylon (PA66-GF) wear ring with a high-performance elastomeric sealing element to deliver superior load-bearing capacity, low friction, and extended service life in both single- and double-acting cylinders.
Key Features
Glass-Filled Nylon Construction: 30% glass-fiber-reinforced polyamide provides exceptional compressive strength, dimensional stability, and resistance to extrusion under high-pressure conditions.
Low Friction Performance: Smooth bore contact minimizes stick-slip and reduces heat generation, protecting cylinder surfaces and seals from premature wear.
Wide Temperature Range: Rated for continuous operation from -40°F to +250°F (-40°C to +121°C), suitable for industrial, agricultural, and mobile hydraulic systems.
Chemical Resistance: Compatible with petroleum-based hydraulic fluids, biodegradable esters, water-glycol fluids, and most common hydraulic media.
Precision Machined Grooves: Tight dimensional tolerances ensure consistent sealing force and easy installation into standard piston groove profiles.
Complete Assembly: Includes piston seal ring and backup/anti-extrusion element for a ready-to-install, drop-in replacement solution.
Typical Applications
Industrial hydraulic cylinders
Agricultural and construction equipment
Mobile hydraulics and off-highway machinery
Pneumatic and low-pressure hydraulic actuators
Upgrade your cylinder rebuild with a seal assembly built to perform — fewer leaks, longer intervals, and reliable operation shift after shift.
