Truegard Lubrication Oils

Specially designed for the lubrication of machine tool slides, tables, and feed mechanisms. These products offer enhanced tackiness and stick-slip characteristics, combined with superior frictional performance on slideways. They are especially recommended in cases where high exposure to soluble cutting fluids exists.

Truegard Heat Transfer Fluids

Propylene glycol heat transfer fluids with industrial corrosion inhibitors are suitable for closed-loop, water-based, HVAC, process heating, and cooling applications. Ethylene glycol fluids are specially designed packages of industrial corrosion inhibitors. This fluid is dyed fluorescent pink for leak detection. 

Truegard NSF Certified Coolants

Food-grade inhibited propylene glycol, is designed for antifreeze and heat transfer in food-related industries like winemaking, beer brewing, and meatpacking. 

Truegard Coolants

Designed for a wide variety of grinding and machining operations on steel, copper, titanium, and aluminum alloys.

Truegard USP Certified Fluids

USP-labeled food-grade propylene glycol, meeting purity standards, is suitable for use in food-related products in small quantities. Certified Kosher by the Chicago Rabbinical Council, it is packaged under "White Room" conditions. Certification  

Truegard Isopar Fluids

Isopar fluids contain extremely low levels of impurities such as benzene, sulfur, heavy metals, and polyaromatic hydrocarbons. They are extensively used as a viscosity-reducing agent for personal care products due to their compatibility with many non-polar ingredients and spreadability properties.

Truegard Mineral Gear Oils

This is the perfect lubricant (mineral-based) for machines used in food and beverage processing and packaging. It combines a food-grade base fluid with dispersants carefully selected to meet industry standards.

Truegard Hydraulics

Designed for use on low-pressure, light-duty hydraulic equipment. Applications include forklifts, air tools, and light-duty presses.

Truegard Anti-Wear Oils

Premium performance mineral-based hydraulic fluids prevent wear with patented Truegard additive technology in combination with high-quality base oils to meet the requirements of a wide range of industrial and mobile hydraulic applications. Used in garage trucks, backhoes, and industrial machines. 

Truegard Gear Oils

Designed for heavy-duty, continuous operation as well as shock loading on all types of industrial steel and bronze gearing. The lighter grades may be used to lubricate highly loaded bearings where common machine oils do not provide the necessary extreme pressure properties. The thicker grades are exceptional worm gear oils.
