TRANSMATEC EP-5 80W-90 - Biodegradable Hydraulic Oil
TRANSMATEC EP-5 80W-90 is a robust extreme-pressure gear and axle lubricant engineered for heavy-duty transmissions, differentials and gearboxes.
Formulated from high-quality base oils and powerful EP (extreme-pressure) additive system, EP-5 provides hard-working protection against wear, scuffing and micropitting while delivering dependable performance across a wide range of commercial, agricultural and industrial applications.
Particularly suited for use in hypoid gears in axles operating under various high speed/low torque and low speeds/high torque conditions.
Recommended Applications
- Manual gearboxes, final drives and hypoid differentials in trucks, buses and trailers
- Agricultural tractors, harvesters and farm implements with conventional gear sets.
- Construction, quarry and off-highway equipment subject to heavy stock loads
- Industrial enclosed gearboxes, reducers and bevel gears operating under high pressure
- Suitable where API GL-5 or equivalent extreme-pressure lubricant performance is required (always confirm OEM Spec)
- Suitable for: API GL-5 MIL-L-2105D. Suitable for use in a non-synchronised manual transmissions and hypoid geared axles that require an API GL-5 lubricant
Key Benefits
- Superior Extreme-Pressure Protection: EP additives form a sacrificial film to prevent metal-to-metal contact under heavy loads and shock
- Excellent Anti-Wear & Anti-Scuff Performance: Extends life of gears, bearings and splines
- Corrosion and Rust Prevention: Protects components during storage and intermittent operation
- Good Thermal & Oxidation Stability: Resists viscosity increase and varnish formation for long service life
- Smooth, Quiet Operation: Helps reduce gear noise and vibration under mixed loads
- Water Tolerance & Demulsibility: Separates readily from water, reducing damage from contamination
- Wide Temperature Usability: SAE 80W-90 gives good cold-start flow with a strong operating film at running temperature
