CR 060002-7

Frequently Asked Questions

Q: What are the exact dimensions and material specifications for the CR 060002-7 O-ring?
A: The CR 060002-7 is an AS568-018 size O-ring manufactured in nitrile rubber (Buna-N) with a durometer of 70 Shore A. Dimensions are 0.739 inches inner diameter (ID) with a 0.070 inch cross-section (CS). This is an OEM Crown part designed for electric lift truck hydraulic service applications.

Q: Which Crown electric lift trucks is the CR 060002-7 O-ring compatible with?
A: The CR 060002-7 is an OEM Crown part for electric lift trucks. Verify your truck model and serial range match this O-ring size before ordering. Cross-reference your equipment documentation or contact our parts team to confirm fitment for your specific Crown model.

Q: Why is nitrile rubber used for this O-ring instead of other elastomers?
A: Nitrile rubber provides excellent resistance to petroleum-based hydraulic fluids, synthetic oils, and water contamination—all common in hydraulic systems on lift trucks. The 70 Shore A hardness balances elasticity with durability, resisting extrusion under hydraulic pressure while maintaining flexibility for dynamic sealing.

Q: What is the expected lifespan of the CR 060002-7 O-ring in typical hydraulic applications?
A: Nitrile O-rings typically last 3 to 10 years in hydraulic service, depending on operating temperature, fluid type, and duty cycle. Crown truck hydraulic systems operating at normal temperatures (40-80 degrees Fahrenheit) can expect mid-to-long service life. Replace if you observe leaks, hardening, or loss of seal pressure.

Q: Are there any alternative part numbers for the Crown CR 060002-7?
A: The CR 060002-7 is the OEM Crown part number. No direct cross-references or superseded equivalents are documented. Always verify the AS568-018 size specification and 70 Shore A durometer when sourcing replacements to ensure correct fitment in your hydraulic circuit.
