Documented formulation and performance
PDS revised 03/06/2023
U1P-DUTY Transmission Drivetrain Torque Fluid is a high-performance multi-purpose transmission and drivetrain fluid designed for powershift transmissions, final drives, wet brakes, differentials, hydraulic systems, and power-steering units in many different newly developed and older makes of transmissions, tractors and heavy-duty equipment requiring TO-4 or C-4 specification. U1P-DUTY Transmission Drivetrain Torque Fluid is formulated with high viscosity-index type II paraffinic base stocks and Ultra-premium performance additives including detergent, anti-wear, anti-corrosion, extreme pressure, dispersants, and anti-foaming agents. The additive protection provides maximum gear life and torque transmission capacity for wet brakes and power-take-off clutches, excellent wet brake noise suppression and filterability characteristics for exceptional fluid cleanliness and equipment reliability. This oil is specially blended to prevent rust, corrosion, foaming and oxidation, to offer excellent torque transmission, seal compatibility and viscosity stability for a constant outstanding performance over the whole life of the lubricant, protecting against wear even in the most severe high loads extreme temperature service conditions. U1P-DUTY Transmission Drivetrain Torque Fluid is available in SAE 10W, SAE 30, and SAE 50 viscosity grades.
Documented benefits
- Minimal downtime: Complete compatibility with seals, clutch, O-rings, and packing materials maintains their good condition, securing proper operation and minimizing leaks
- Long equipment life and smooth operation: Excellent frictional control helps prevent clutch slippage and offers quiet and efficient torque transmission and brakes action while minimizing wear
- Long oil life: The high viscosity-index type II paraffinic base stock withstands oxidation at high operating temperatures resulting in maximum oil service life
- Reliable operation and Equipment protection: U1P-DUTY Transmission Drivetrain Torque Fluid prevents the formation of corrosion, varnish, and sludge, avoiding premature breakdowns and protecting all internal metal and highly finished precision parts against rust and wear, when operating under high load and/or humid conditions, and during seasonal shutdown storage periods
