5. FAQ

Q: How do I install these seal rings correctly?
A: Clean the groove and mating surfaces thoroughly, lubricate the rings with compatible hydraulic oil, install them evenly without twisting or scratching, and ensure they sit fully in the groove before assembling the parts.
 
Q: What are the most common causes of seal ring failure?
A: Common causes include installation damage like pinching or scratching, contaminated hydraulic fluid causing abrasion, excessive pressure leading to extrusion, and surface defects on mating components that wear the ring over time.
 
Q: How long do these seal rings typically last?
A: Under normal conditions with clean fluid and proper installation, high-quality PTFE or PU seal rings can last 3,000–6,000 operating hours, depending on the application and cycle rate.
 
Q: Can I reuse old seal rings?
A: No, it is never recommended to reuse these seal rings. Once installed and exposed to operating conditions, the rings develop permanent wear, deformation, or surface damage. Even if they look fine, they will not form a reliable seal when reinstalled, leading to leaks or pressure loss. Always use new seal rings during every rebuild.
