Hydraulic Backup Ring for New Holland T4/T4000/T5/T6000 Series Tractors SKU: QT400165

A worn backup ring allows primary hydraulic seals to extrude into clearance gaps under high pressure, causing seal damage and catastrophic fluid loss. This backup ring provides essential support for your tractor's hydraulic seals, preventing extrusion and maintaining system integrity during demanding hydraulic operations.

Why This Component Matters

• Prevents primary seal extrusion in high-pressure hydraulic applications
• Made from durable materials engineered for agricultural hydraulic service
• Essential support component for reliable cylinder and pump seal performance
• Prevents seal damage that leads to costly hydraulic system failures

Working alongside primary seals in hydraulic cylinders, pumps, and steering systems, backup rings are critical for maintaining proper sealing under the extreme pressures your New Holland tractor generates. Without proper backup ring support, even new primary seals fail quickly when subjected to the 2,500+ PSI pressures common in modern hydraulic systems.
