Stack Pipe O-Ring for Hydraulic Valve Applications SKU: QT195561

When hydraulic valves develop internal leaks or lose pressure, worn O-rings are often to blame. This specialized stack pipe O-ring provides the precise sealing needed to maintain proper hydraulic pressure within valve assemblies, preventing costly fluid loss and restoring system performance.

Why This Seal Matters

• Precision dimensions ensure perfect fit in hydraulic valve stack configurations
• Oil-resistant rubber compound withstands hydraulic fluid and temperature extremes
• Maintains critical pressure integrity for reliable valve operation
• Prevents internal bypassing that causes sluggish hydraulic response

Stack pipe assemblies are critical components in hydraulic valve blocks where multiple valves are mounted together. A failed O-ring in the stack can cause pressure loss affecting the entire hydraulic system. With over 55 years of parts experience, S&H Parts stocks the seals you need to keep your equipment working.
