QUAD RING
Frequently Asked Questions
Q: What is a quad ring and how does it differ from a standard O ring?
A: A quad ring (also called a quad seal) is a four-lobed seal design compared to the round cross-section of a standard O ring. Quad rings provide better pressure distribution, lower extrusion risk, and improved sealing performance in dynamic (moving) applications. The MI 2-22ON674-70 quad ring is designed for Mitsubishi electric lift truck systems where enhanced sealing is required.
Q: Which Mitsubishi equipment uses the MI 2-22ON674-70 quad ring?
A: The MI 2-22ON674-70 is specified for Mitsubishi electric pallet jacks and lift truck cylinder assemblies where dynamic seal performance is critical. Verify your equipment model and cylinder specification match this OEM part number. Contact us with your truck model if you need confirmation.
Q: What are the size specifications for the MI 2-22ON674-70 quad ring?
A: The SKU designation MI 2-22ON674-70 identifies the bore diameter and cross-section of this quad seal. For exact dimensions in millimeters, consult your Mitsubishi equipment documentation or contact our technical team. Precise size matching is critical for proper seal function.
Q: Does the MI 2-22ON674-70 quad ring require different maintenance than a standard O ring?
A: Quad rings require the same maintenance principles as standard O rings: keep the system clean, maintain proper fluid levels, and monitor for leaks. The quad ring design provides extended lifespan and better performance under pressure fluctuations. Replace when leaks appear or system pressure drops.
Q: Can I replace a standard O ring with the MI 2-22ON674-70 quad ring?
A: Only if your Mitsubishi truck specification calls for a quad ring and the bore size matches exactly. The quad ring design is not interchangeable with standard O rings of different profiles. Always use the OEM-specified seal type for your equipment model to ensure proper performance.
