Renewable Lubricants ISO 68 Hydraulic Oil

This vegetable-based hydraulic fluid is formulated for industrial, marine, and mobile equipment requiring zinc-free lubrication. It suits high-pressure systems, servo valves, NC control mechanisms, and robotics where bio-food grade certification is necessary. The light yellow fluid comes in a one-gallon jug for convenient handling and storage.

Installing and topping up hydraulic systems

Pour the fluid directly into the reservoir after confirming the system requires ISO viscosity grade 68. Contamination is the most common issue; always clean fill ports and use filtered funnels to prevent dirt or water ingress. Mixing with mineral-based or other fluid types can degrade performance and damage seals, so a full flush is recommended when switching fluid chemistries.

Verifying system requirements before ordering

Check the equipment manual to confirm the specified viscosity grade matches ISO 68 and that zinc-free, bio-food grade fluid is approved. Ensure the hydraulic system operates within the pressure and temperature ranges suitable for this formulation. Verify seal and hose material compatibility with vegetable-oil base stocks to avoid premature leakage or swelling.
