Safety Data Sheet

Frequently asked questions

Find answers to common questions about our products and services

  • This fluid is designed for hydraulic systems operating under pressure near open flames or in high-temperature areas. It is particularly well-suited for car washes and forging operations, where fire resistance is a critical safety requirement.

  • Because Houghton-Safe 620 is a water glycol type fire-resistant hydraulic fluid, it does not exhibit a conventional flash point or fire point the way petroleum-based hydraulic fluids do. This is the characteristic that makes it suitable for environments near open flames or high heat.

  • A viscosity index of 200 means the fluid's thickness changes relatively little across a wide temperature range, allowing it to maintain consistent hydraulic performance in both cold and high-temperature operating conditions.

  • Houghton-Safe 620 has a pour point of -50°F, which provides excellent stability and flow in cold-weather conditions. Its high viscosity index further supports consistent performance across varying temperature environments.

  • Yes, Houghton-Safe 620 is also available in 5-gallon pails for applications that require smaller quantities.

  • The fluid was evaluated using the ASTM D-2882 procedure with a Vickers V-104-C pump, run for 100 hours at 2,000 psi discharge pressure, 150°F fluid temperature, and 1,200 rpm. Test results showed 29.4 mg of cam ring wear and 2.4 mg of vane set wear over the full test period.

Key Features

  • Factory Mutual approved as a fire resistant hydraulic fluid, helping protect personnel and property from accidental fire in high-pressure, high-temperature, and open-flame environments.

  • Water glycol formula carries no flash point or fire point, making it well suited for car wash and forging applications where fire hazard is a concern.

  • Pour point of -50°F delivers excellent stability and reliable performance in cold weather applications.

  • Viscosity index of 200 allows the fluid to perform across a wide operating temperature range, from cold startups to high-heat conditions.

  • Excellent lubrication characteristics extend pump and component life, as demonstrated by low cam ring and vane wear results under ASTM D-2882 testing with a Vickers V-104-C pump.
