Phillips 66® T5X Off-Road Mobile Hydraulic Fluid is a high-performance hydraulic fluid designed primarily for use in the hydraulic systems of Caterpillar and other off-highway mobile equipment. It also may be used in the hydrostatic transmissions of some off-road equipment.
• High viscosity index for use over a wide temperature range
• Excellent wear protection for hydraulic system components
• High dispersancy-detergency for excellent system cleanliness
• Protects against deposit formation
• Protects against rust and corrosion
• Good resistance to foaming
• Hydraulic systems and some hydrostatic transmissions on Caterpillar and other off-highway mobile equipment
• Hydraulic systems operating over a wide temperature range
