TC 03340-00060

Frequently Asked Questions

Q: What are the exact dimensions and material of the TC 03340-00060 O-ring?
A: The TC 03340-00060 is a metric nitrile (Buna-N) O-ring with 4.5 mm inner diameter and 1.5 mm cross section, rated at 70 Shore A durometer hardness. It meets JIS S5 standards for Japanese industrial equipment. These dimensions place it in standard metric sizing for compact seal applications in electric lift trucks.

Q: Which electric lift truck systems use this O-ring?
A: The TC 03340-00060 is specified for static and dynamic sealing in hydraulic systems and lift mechanisms of electric lift trucks from Crown, Toyota, Raymond, Hyster, and other OEMs using this dimension. It typically seals pump ports, valve connections, or actuator rod seals. Verify your equipment manual lists this exact part number before ordering.

Q: How does the 70 Shore A durometer affect performance and durability?
A: 70 Shore A is a medium durometer suitable for general hydraulic sealing at moderate pressures and temperatures. Nitrile at this hardness resists ISO 46 mineral hydraulic oil and maintains flexibility over a -20 to 100 degree Celsius range. It offers better longevity than harder durometers in dynamic applications but less resistance to extreme temperatures or aggressive solvents.

Q: What is the service life of the TC 03340-00060?
A: Under typical electric lift truck operating conditions with clean hydraulic fluid and controlled temperature, this O-ring has an expected service life of 3 to 5 years. Life decreases with system overheating, contaminated fluid, or constant high-pressure cycling. Replace immediately if you observe cracks, hardening, loss of seal pressure, or fluid leakage.

Q: Is there a cross-reference or equivalent part for the TC 03340-00060?
A: The TC 03340-00060 follows JIS S5 metric O-ring sizing. OEMs may assign different part numbers to this same dimension, so cross-reference by confirming 4.5 mm ID and 1.5 mm cross-section with your equipment manual. Verify the material is nitrile 70 Shore A to ensure compatibility with your hydraulic system.

Q: What maintenance or storage is required for this O-ring?
A: Store the TC 03340-00060 in a cool, dry location away from direct sunlight and ozone sources to prevent premature hardening. O-rings require no maintenance once installed. If your equipment shows signs of hydraulic leakage from seal locations, or if system pressure drops below normal operating range, inspect and replace the O-ring.
