Hydraulic System O-Ring for New Holland T4/T4000/T5/T5000/T6/T6000/T9 Series Tractors SKU: QT400159

A failed O-ring in your hydraulic system creates more than just a mess - it robs your tractor of the pressure needed for loader work, three-point control, and remote hydraulics. Hydraulic fluid leaking means money and time wasting away while your equipment loses the power it needs for critical operations.

Why Proper Sealing Matters

• Maintains hydraulic pressure for reliable loader and implement operation
• Prevents contamination that damages expensive pumps and valves
• Engineered for high-pressure hydraulic systems in demanding farm conditions
• Precise fit prevents internal bypassing that reduces hydraulic efficiency

Your New Holland T-series tractors depend on hydraulic power for everything from front-end loaders to three-point implements and remote cylinders. These modern workhorses running multiple hydraulic functions require proper fluid level and pressure to perform when you need them most.
