Guardian FM Hydraulic Oil

Guardian FM Gear Oil

Guardian FM Greases

Guardian Food Machinery Hydraulic Oil offers performance equal to conventional premium industrial AW hydraulic oil and is used in a variety of applications where hydraulic fluid is required. The robustness built into this oil means that it can be applied virtually anywhere you would use conventional hydraulic oil. No misapplication. In almost all applications, Guardian FM Hydraulic Oil allows you to operate your hydraulic systems at OEM-recommended operating conditions just like you would with a premium industrial AW hydraulic oil.

Guardian Food Machinery Gear Oil is fortified with food grade antiwear agents and a tackiness agent to provide maximum antiwear and clinging characteristics so it can withstand rust and oxidation and stays thick at high temperature.

Guardian FM Grease is an Aluminum-Complex thickened grease, formulated with food grade base oils. It has a higher dropping point and excellent rust protection as compared to conventional aluminum-complex greases and meets the NSF H1 requirement.

Guardian FM Gear Oil offers better or equal performance to industrial gear oils in a number of areas, including oxidation stability and scuffing protection. Guardian prolongs gear life and provides outstanding scuffing protection as demonstrated by its performance in the FZG Scuffing test. It can be used in applications both above and below the food line and does not thin out or thicken from oxidation at high temperatures.

Guardian Crystal FM Grease is a unique synthetic grease formulated from synthetic base oils and a proprietary “in-organic” silica thickener system. It has a high amount of EP and Adhesive additives that give it a High Load capability, no dropping point and is a no-melt type of grease. It has a unique transparent color.

Guardian offers premium anti-wear protection against higher pressure and operating temperatures for improved pump durability, foam control, rust protection and sludge control. Guardian FM Hydraulic Oil offers performance equal to a conventional premium Industrial AW Hydraulic Oil

Seal Compatibility



NSF H-1, Kosher, Halal



Guardian FM Hydraulic and Gear Oils offer very good seal compatibility. Controlling lubricant leakage is critical in Food and Beverage Processing. Using lubricants that are not compatible with seals can lead to lubricant leakage which can contaminate food, creating a messy workplace, and increasing the need to add makeup oil. Shortened seal life increases the risk of external contaminants entering the hydraulic system and gear box. Abrasive particles from deteriorated seals can also accelerate wear.

Guardian helps eliminate pump cavitation by reducing the air in the oil for better equipment efficiency.

Scuffing Wear Test

Foam control for extended pump life and improved housekeeping.

Provides an extra layer of protection to reduce wear on critical parts.

Oil with poor foam control


Guardian oil with low foam


Guardian helps reduce sludge to extend pump and filter life, reduce downtime and provide faster hydraulic system response time. Guardian FM Hydraulic Oil reduces tendency to filter plugging through the life of your hydraulic equipment. Superior sludge / deposit control results from our ability to stabilize the thermal and oxidative qualities of the oil. 80

Guardian helps control wear to increase your pump and gear box durability. Guardian provides outstanding protection against scuffing in hydraulic pumps and gear boxes as demonstrated by its performance in the FZG Scuffing test: 12 load Stage Pass.


A key indicator of fluids’ ability to control wear is its performance in controlled pump testing. Guardian FM Hydraulic Oil maintains strong wear protection comparable to premium industrial AW Hydraulic Oil, giving you the confidence for extended pump durability.
