Frequently asked questions

Find answers to common questions about our products and services

  • Houghton-Safe 620 is a water glycol type fire resistant hydraulic fluid. Because it is water-based, it does not have a measurable flash point or fire point, which is what makes it inherently fire resistant and safe for use under pressure, near open flames, or in high-temperature environments.

  • The pour point is -50°F, providing excellent stability in cold weather applications. A viscosity index of 200 allows the fluid to maintain consistent performance across a wide temperature range, with viscosity data available from 0°F through 130°F.

  • It provides excellent lubrication characteristics that extend pump and component life. Pump testing per ASTM D-2882 using a Vickers V-104-C pump at 2,000 psi over 100 hours produced low wear results: 29.4 mg cam ring wear and 2.4 mg combined vane set wear.

  • Houghton-Safe 620 is Factory Mutual approved as a fire resistant hydraulic fluid designed to protect personnel and property from accidental fire. This Factory Mutual approval may also lower insurance premiums for facilities using it.

  • Yes, it is recognized by Original Equipment Manufacturers and is available globally, making it a widely accepted choice for industrial hydraulic systems requiring fire resistant fluids.

  • Yes, Houghton-Safe 620 is also available in 55-gallon drums for higher-volume applications.
