Royco 783

ROYCO 783

MINERAL BASED HYDRAULIC FLUID
PRESERVATIVE GRADE

GENERAL INFORMATION:

ROYCO 783 is a red colored petroleum based, low viscosity hydraulic fluid and preservative oil developed to meet the severe duty demands of today's military and industrial equipment. Modern additive technology is employed
for high oxidation and shear stability, rust and corrosion inhibition, and anti-wear protection.

APPLICATIONS:
ROYCO 783 is intended for use in severe duty applications requiring low temperature operation, excellent shear stability, water demulsibility, and extended time periods between service intervals. ROYCO 783 is recommended for use in aircraft, missile, and ordnance systems using synthetic sealing material as well as heavy-duty construction equipment, and industrial robotic hydraulic systems. ROYCO 783 is suitable for use at operating temperatures from -40 to 275oF. This product is especially recommended for use in artillery recoil mechanisms,
hydraulics used in rotary weapons systems, and armored vehicles.

ADVANTAGES:
Low temperature fluidity
Excellent shear stability
Improved water demulsibility
Reduces wear and deposit build-up

COMPATABILITY:
ROYCO 783 should not be used in hydraulic systems with natural rubber elastomers.

APPROVALS:
ROYCO 783 meets all requirements of and is qualified to the latest revision level of MIL-SPEC: MIL-PRF-6083F.
