KLÜBER to Shell Compressor Oil Cross-Reference Table
| KLÜBER Product | Equivalent Product | Compatibility & Notes |
| Klubersynth RA 4-46 | Shell Corena S4 R 46 | Both PAO synthetic rotary screw compressor oils. Extended service life vs mineral compressor oils. |
| Klubersynth RA 4-68 | Shell Corena S4 R 68 | Synthetic compressor oils for higher-temperature rotary screw operation. Verify OEM approval list. |
| Klubersynth RA 4-100 | Shell Corena S4 R 100 | Higher viscosity synthetic for high-temperature and high-pressure compressor applications. |
| Klubersynth UH1 6-68 | Shell Naturelle HF-E 46 | Food-grade compressor oils — different base oils (PAO vs ester). Verify NSF H1 requirements. |

⚠ Important Disclaimer
This cross-reference is provided for informational purposes only. Equivalent does not mean identical — differences in thickener type, base oil viscosity, additive packages, and NLGI grade can affect performance. Always verify technical compatibility by consulting both manufacturers' datasheets and obtaining OEM approval before substituting lubricants. Contact KOEED for verified KLÜBER product recommendations matched to your specific application requirements.
> Tip
When cross-referencing, always verify: (1) thickener compatibility — mixing incompatible thickeners can cause grease to soften or harden, (2) base oil viscosity at operating temperature, (3) NLGI grade for proper consistency, (4) certification status (NSF H1, ISO 21469) for food-grade applications. If in doubt, contact KOEED for a verified recommendation.
Frequently Asked Questions
Q: What are the benefits of synthetic compressor oil?
Synthetic (PAO) compressor oils offer 4-6× longer service life compared to mineral compressor oils, reduced varnish and deposit formation, lower oil carryover, and better high-temperature stability. The extended drain interval typically offsets the higher initial cost, especially in continuous-duty industrial compressors.
