Truegard Soluble 384 is the go to soluble coolant for versatile metalworking applications. This multi-purpose heavy duty coolant can machine aluminum alloys, titanium, Inconel, stainless steel, and all automotive steels.

At Keller-Heartt Oil, we are proud to carry TRUEGARD soluble 384 coolant in 275 gallon totes for high volume metalworking applications. TRUEGARD Soluble 384 is a general purpose soluble oil for light to moderate duty machining on a wide range of materials.

TRUEGARD Soluble 384 coolant is high mineral oil containing soluble for easy to medium duty machining, including grinding, on a wide variety of materials including as well ferrous as non-ferrous metals.

Benefits:

  • Bio-Stable formula reduces the need to dispose coolant, and saves on adding additional new coolant
  • No need for sump additives
  • Excellent lubricity and extreme pressure additives provide extended tool life, and increase production
  • Outstanding corrosion protection - for both machine and workpieces - provides parts protection


Recommended Mixture:

  • General Machining: 6-9%
  • Grinding, Lith Machining: 3-4%
  • Refractometer Factor: 1.1


Typical Values:

  • Appearance: Amber
  • 5% Appearance: White
  • PH In Use: 8.2-8.7

Frequently asked questions

Find answers to common questions about our products and services

  • Soluble 384 is designed for light to moderate duty machining and grinding across a wide range of materials, including aluminum alloys, titanium, Inconel, stainless steel, and all automotive steels, as well as both ferrous and non-ferrous metals in general. This broad compatibility makes it a practical choice when a single coolant needs to handle diverse workpiece materials on the same machine.

  • Yes, the recommended mixture varies by application: use 6-9% for general machining and a lower 3-4% for grinding or light machining. Running at the correct concentration is important because too lean a mix reduces lubricity and corrosion protection, while too rich a mix wastes product and can cause residue buildup.

  • A refractometer factor of 1.1 means you must multiply your refractometer reading by 1.1 to get the true concentration in the sump - for example, a refractometer reading of 5% actually indicates a 5.5% concentration. This correction is necessary because soluble oils bend light differently than plain water, and using the raw reading without the factor would cause you to over-concentrate the mix.

  • Bio-stable means the formula is resistant to microbial degradation, so the coolant stays usable in the sump for longer without breaking down or developing odor-causing bacteria at the rate conventional soluble oils do. According to the product data, this bio-stable formulation eliminates the need for separate sump additives, reducing maintenance steps and overall coolant management costs.

  • The in-use pH should be maintained between 8.2 and 8.7, which is a mildly alkaline range. Staying within this range is important because it supports both corrosion inhibition on metal surfaces and a hostile environment for microbial growth; a significant drop below this range is typically a sign that the coolant is degrading and may need to be refreshed.

  • The product provides corrosion protection for both the machine and the workpieces being machined. This dual protection helps prevent rust on machine slideways, spindles, and coolant system components, which is especially important in humid shop environments or when machining ferrous materials that generate rust-prone swarf.
