O Ring

Frequently Asked Questions

Q: What is the ME 2712 O-ring used for?
A: The ME 2712 is a hydraulic O-ring seal for electric lift trucks. It seals pump shafts, hydraulic cylinders, valve assemblies, and hose connections to prevent fluid leakage and maintain system pressure.

Q: What are the dimensions of the ME 2712 O-ring?
A: The ME 2712 has an inner diameter of 1.25 inches and cross-section diameter of 0.125 inches. These dimensions fit standard metric 32mm hydraulic ports and SAE shaft seals. Verify bore diameter matches your equipment before ordering.

Q: What material is the ME 2712 O-ring made from?
A: This O-ring is made from nitrile rubber (NBR) with a Shore A hardness of 70. Nitrile provides excellent resistance to hydraulic oils, water, and temperature ranges from minus 40 to 212 degrees Fahrenheit, standard for lift truck environments.

Q: Which lift truck brands use the ME 2712 O-ring?
A: The ME 2712 is compatible with Crown, Toyota, Raymond, Yale, Hyster, and Mitsubishi electric lift trucks. This is a universal hydraulic seal, so cross-reference your specific hydraulic component or pump assembly to confirm fit.

Q: What is the typical replacement interval for the ME 2712 O-ring?
A: O-rings typically last 3 to 5 years depending on hydraulic fluid condition and operating temperature. Leakage, seepage, or loss of lift pressure indicates seal failure. O-rings cannot be cleaned or reused and must be replaced. Replace all O-rings in a component assembly to prevent cross-contamination.
