Synthetic TBI ISO 32/46 Biodegradable Hydraulic Oil

  • Denison HF-0, HF-1, HF-2

  • Vickers M-2950-S, I-286-S

  • Cincinnati Milacron P-68, P-70

AMSOIL TBI hydraulic oil is a premium lubricant designed to biodegrade to its natural state when subjected to sunlight, water and microbial activity. Because it is formulated with ashless additives that do not contain heavy metals, TBI has a very low toxicity level.

AMSOIL TBI incorporates very high-quality synthetic base oils that provide thermal stability, even though they are biodegradable. TBI also contains antiwear additives that have been thoroughly tested and qualified against stringent hydraulic oil standards including Denison HF-0, HF-1 and HF-2, Vickers M-2950-S and I-286-S and Cincinnati Milacron P-68 and P-70. TBI provides optimum protection for hydraulics, preventing pump wear and rusting of critical components. It also contains antioxidants that increase oil life and foam inhibitors that quickly release air from the oil.

Based on high-quality, synthetic oil chemistry that better withstands heat and lasts longer, TBI outperforms vegetable oil-type, biodegradable hydraulic oils, ensuring problem-free operation.

Application Recommendation

AMSOIL TBI is recommended for gear, vane and piston stationary and mobile hydraulic systems. TBI is a multi-viscosity, SAE 5W-20 oil and is recommended for use in place of either ISO-32 or ISO-46 hydraulic oils.

TBI is essentially compatible with typical hydraulic oils, and small amounts of contamination (lines, residue) are acceptable. However, it is recommended systems be drained prior to installing TBI. Excessive system contamination will minimize its biodegradability effectiveness.

TBI is especially well suited for applications where environmental contamination due to leaking or blown hydraulic lines presents an environmental hazard.

TBI has been tested and found compatible with Nitrile (Buna-N), Poly Acrylate, Fluorocarbon (Viton) and Silicone seals which are commonly found in hydraulic systems.

The ability of TBI to extend drain intervals and excel in performance is subject to operating conditions and maintenance practices. Monitoring by oil analysis is recommended.
