FR Fluid-Glycol

# LBPH814640

Water-Glycol Based Fire-Resistant Hydraulic Fluid

Phillips 66® FR Fluid-Glycol is a water-glycol based fire-resistant hydraulic fluid developed for use in industrial hydraulic systems operating in areas subject to fire hazards. It contains sufficient water to snuff out a fire resulting from ignition of a fluid leak. It is suitable for use in hydraulic systems operating at 2,000 to 3,000 psi, and can withstand intermittent pressure spikes up to 5,000 psi.

Features & Benefits
