Rectangular Hydraulic Backup Ring for Farm Equipment Systems SKU: QT0634402541

Hydraulic systems develop internal leaks when backup rings fail, causing pressure drops and component failures. This rectangular backup ring provides the critical support that primary seals need to maintain proper compression and prevent extrusion under high pressure operation.

Why Backup Rings Matter

• Prevents primary O-ring extrusion in high-pressure applications
• Maintains seal integrity during pressure cycles and temperature changes
• Engineered to handle demanding agricultural hydraulic conditions
• Supports proper seal compression to prevent premature failure

When hydraulic cylinders start bypassing or you notice decreased system pressure, failed backup rings are often the hidden culprit. These critical seals keep fluids where they belong and prevent the leaks that lead to bigger problems. With over 55 years of hydraulic parts experience, S&H Parts stocks the backup rings that keep farm equipment running.
