Hydraulic Oils

There are dozens of different types of hydraulic oils for general and specialty hydraulic applications, hydraulic oil function and maintenance. These oils can be sorted by their base oils or performance characteristics. Hydraulic oil characteristics that are important for determining the appropriate hydraulic oil include: viscosity, viscosity index, base oil, operating temperature range, anti-wear requirements, oxidation stability, corrosion resistance, de-emulsification stability and resistance to foaming.

Listed below are some of our standard hydraulic oils for general and specific applications. This is not a complete list of the available hydraulic oils.

Standard Hydraulic Oils: (Puroil HO Series): Clearly the most common type of hydraulic oil. These products are inexpensive and functional for most hydraulic applications.

Anti-Leak Hydraulic Oils: (Puroil AL Series): Hydraulic oils blended with additives that reduce drip, splatter and reduce leakage.

Synthetic Hydraulic Oils: (Puroil SHO Series): Superior performance over a wide temperature range (-70^oF to 400^oF), these oils are biodegradable and environmentally safe.

Water Based Hydraulic Oils: (PureSafe Series): Inexpensive hydraulic fluid for less severe applications in warm climates.

Fire Resistant Hydraulic Oils: (PureSafe Series): Self extinguishing hydraulic oils for use in applications where high heat and fire risk is a factor and safety needs to be assured.

Food Grade Hydraulic Oils: These hydraulic oils are acceptable as a lubricant with incidental food contact for use in official establishments operating under the Federal Meat & Poultry Products Inspection Program.

Mil-Spec Hydraulic Oils: These hydraulic oils are approved to military specifications.
