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.
