Your trusted partner in hydraulic fluid testing.

About Our Hydraulic Services

Whether you’re involved in aviation, industrial applications, or heavy equipment, our testing services cover fire-resistant aerospace fluids, fire-resistant industrial hydraulic fluids, and general-purpose hydraulic fluids.

Hydraulic fluid producers and hydraulic system manufacturers are constantly testing the limits of hydraulic fluid performance. We perform an extensive range of tests on new fluids in support of R&D and manufacturing quality programs.

We test hydraulic fluid properties including flammability (especially important in aviation applications), viscosity, wear (minimizing metal breakdown from metal-to-metal contact), foaming, corrosion prevention, oxidation and thermal stability, and rubber seal compatibility.

Contaminated or poor-quality hydraulic fluid can cause unnecessary wear and even damage hydraulic systems.

Contamination can be caused by substances such as dirt and by water. Damage may include jamming, wear on parts, and decreased performance. Testing hydraulic fluid can help pinpoint contamination and testing regularly as part of a quality control program can help detect these problems before they cause damage.

Listed below are some of the specifications and tests we can perform on hydraulic fluids. If you don’t see a test that you’re interested in, please contact us. We are always adding capabilities, willing to set up new methods, and have a large network of labs to collaborate with.
