Hydraulic Cylinder Seal Repair Kit for 4 Inch Bore Cross and Hydroline Cylinders with 2 Inch Rod

Description

When your hydraulic cylinders start showing signs of wear—maybe your loader is drifting down while you’re trying to stack hay bales, or your implement won’t hold position like it used to—it’s time to rebuild those seals before you lose hydraulic pressure completely. Worn cylinder seals cause implements to drift down, reduce lifting capacity, and create messy external leaks that waste expensive hydraulic fluid. This comprehensive seal kit brings your 4-inch bore cylinders with 2-inch rods back to factory-tight condition.

What You’re Getting

• Complete seal set that includes all the seals and O-rings you need for a proper rebuild
• High-quality seals designed to handle the constant pressure cycles of loader and three-point operations
• Seal Kits for Hydraulic Cylinders – For Hydroline & Cross compatibility ensures these work with both manufacturers’ cylinders
• Proper durometer ratings to maintain flexibility while providing positive sealing under high pressure

Built for Real Farm Work

These cylinders show up on a wide range of farm equipment, from front-end loaders to three-point lift assemblies. Whether you’re running a compact utility tractor or a mid-size row-crop machine, 4-inch bore cylinders with 2-inch rods are workhorses that handle everything from moving round bales to lifting heavy implements. Hydraulic Cylinders, filter by bore and stroke. Choose from Tie Rod Hydraulic Cylinder and Welded Hydraulic Cylinders.

Made to Last

These seals are engineered to stand up to the tough conditions farm hydraulics face every day. They resist modern hydraulic fluids, handle temperature swings from winter startups to summer heat, and maintain their seal integrity through thousands of pressure cycles. Each seal features the correct durometer rating to maintain flexibility while providing positive sealing under high pressure. The kit includes seals designed to handle the constant pressure cycles of loader and three-point operations.

Installation Notes

Plan on a few hours for a complete cylinder rebuild, and cleanliness is absolutely critical—any dirt or debris will destroy new seals quickly. Take photos as you disassemble to remember how everything goes back together, and replace all the seals even if some look okay since they’ve all seen the same service hours. Use assembly lubricant on the seals during installation, and after the rebuild, consider changing your hydraulic filter and fluid to remove any contamination that might have built up.
