Description
When your hydraulic cylinder starts weeping oil or implements begin drifting down while you’re working, it’s time for new seals. This AgSmart seal kit fits 3.5 inch bore cylinders with 1-1/4 inch rods and includes all the seals you need to restore your cylinder to leak-free operation. No more watching expensive hydraulic fluid drip onto the ground or dealing with implements that won’t hold position.
What You’re Getting
- Complete seal set including piston seals, rod seals, and wiper seals to stop all leaks
- Engineered materials that handle the pressure and temperature swings of farm hydraulics
- Direct replacement seals sized specifically for 3.5 inch bore x 1-1/4 inch rod configurations
- Quality construction that resists wear from contaminated fluid and regular use
Built for Real Farm Work
This seal kit works on hydraulic cylinders commonly found on loaders, three-point systems, and various implements where the cylinder bore measures 3.5 inches and the rod diameter is 1-1/4 inches. Whether you’re lifting hay bales with a loader or adjusting implement depth in the field, these seals are designed to handle the daily demands of agricultural hydraulics.
Made to Last
The key to successful seal replacement is cleanliness – any contamination ruins new seals immediately. These seals are engineered from premium materials that handle the heat, pressure, and chemical properties of modern hydraulic fluids while resisting hardening and cracking from age and heat cycles.
Installation Notes
Cylinder rebuilding requires cleanliness above all else, so disassemble carefully and note orientation of all seals. Install seals using proper tools to avoid damage and lubricate with clean hydraulic fluid during assembly. After rebuilding, cycle slowly at first to seat seals properly. While you’ve got things apart, it’s a good time to check your hydraulic fluid and filter.
