Synthetic fire resistant "Super Clean" hydraulic fluid
ROYCO 782 is a red - colored synthetic hydraulic fluid developed to meet the severe duty demands of today's military and industrial equipment. Modern additive technology is employed for oxidative stability, corrosion inhibition,
and anti-wear protection. ROYCO 782 is compatible with petroleum based fluids and all components used in mineral oil type hydraulic systems.
ROYCO 782 is intended for use in severe duty applications requiring both low and high temperature operation, extended time periods between service intervals, excellent shear stability, water demulsibility, and the safety factor afforded by the use of a synthetic fluid.
ROYCO 782 is recommended for use in aircraft, missile, and ordnance systems using synthetic sealing materials as well as in heavy-duty construction equipment, and industrial
robotic hydraulic systems.
ROYCO 782 is suitable for use in applications operating at temperatures from -40 to 204oC. This product is especially recommended for use where the high flash point provides added safety margins.
As a Vans RV owner I noticed a change in my original 5606 brake fluid and have heard that 5606 if left with bleeding brakes can change from the heat the brakes naturally develop. 782 is a synthetic replacement and compatible with 5606, although I suggest to completely replace it in the system. It has a very high flash point and does not gel or lose its consistency. Lower maintenance and brake reliability is too important.

Q: Can I upgrade to this Anderol Royco 782 hydraulic fluid from MIL-H-5606?
Per the supplier: Yes, you can.
Q: Can ROYCO 782 be mixed with MIL-5606?
No, these cannot be mixed together as they have different specs and contents that may apply to different applications.
