Description

When you notice hydraulic fluid pooling under your tractor or your loader starts moving sluggishly, it’s usually worn cylinder seals telling you they’ve had enough. This seal repair kit gives you everything needed to rebuild your 4-inch bore hydraulic cylinders with 1-1/4-inch rods, getting them back to working like new without the expense of cylinder replacement.

High-quality seals that resist heat, pressure, and hydraulic fluid exposure
Direct replacement components – no modifications or adapters needed
Internal seals to maintain pressure and external seals to prevent fluid loss
Manufactured from materials specifically chosen for hydraulic service

Built for Real Farm Work

These cylinders are found on larger tractors and implements doing heavy lifting on loaders, big disc harrows, and heavy-duty three-point implements. Whether you’re moving dirt, lifting round bales, or working ground, these cylinders see plenty of action and need reliable sealing. This size cylinder is commonly used where you need substantial power for demanding tasks around the farm.

Made to Last

Farm equipment operates in harsh conditions, and these seals are built to handle it. The seal material stays flexible in cold weather and won’t harden up from heat or hydraulic fluid exposure, keeping them working season after season.

Installation Notes

Cylinder rebuilding requires cleanliness above all else – any contamination causes rapid seal failure. Disassemble carefully, noting orientation of all seals, and clean all components thoroughly. Install seals using proper tools to avoid damage and lubricate with clean hydraulic fluid during assembly. Take your time and work clean for the best results.
