Description

When you’re dealing with hydraulic cylinder repairs or rebuilding hydraulic components on your tractor, you know that half the job is getting the sealing system right. This backup ring might be small, but it plays a crucial role in keeping your hydraulic seals working properly under pressure. It’s the unsung hero that prevents seal extrusion and keeps your hydraulics holding pressure like they should.

Key Features

Prevents primary seals from extruding under high pressure – keeps them in place where they can do their job
Made from durable materials that handle the pressure spikes and temperature changes common in hydraulic systems
Precise dimensions ensure proper fit in hydraulic cylinder grooves and valve assemblies
Essential component for proper hydraulic seal installation – not an optional part you can skip

Built for Real Farm Work

This backup ring fits a wide range of Case IH and New Holland tractors, from utility models like the JX series up through mid-size tractors in the Maxxum and MXU lines. Whether you’re fixing a leaky lift cylinder, rebuilding remote valve assemblies, or overhauling hydraulic components, this ring ensures your seals stay put when the pressure builds up.

Made to Last

Hydraulic systems create enormous pressure – sometimes over 3000 PSI in modern tractors. Without proper backup rings, primary seals can get forced out of their grooves and fail quickly. This ring is engineered to handle those pressure loads while maintaining its shape and position, giving your seals the support they need for long-term reliability.

Good to Know

Always install backup rings on the low-pressure side of the primary seal – they’re designed to prevent extrusion, not create the main seal. Keep them clean during installation and check that they sit properly in their grooves. When rebuilding cylinders, it’s smart to replace backup rings even if they look okay – they’re inexpensive insurance against seal failure.
