Schaeffer 238 Ultra Supreme Waterproof Grease

NLGI #1, #2 & #3

Ultra Supreme Waterproof Grease is a multi-purpose, aluminum complex grease made from severely hydrotreated polyalphaolefin (PAO) synthetic base oils, and severely hydro-finished 100% paraffin base stocks with a high viscosity index. Designed for durability, Ultra Supreme withstands the demands of heavy-duty automotive and off-road equipment.

Ultra Supreme quickly lubricates metal surfaces, offering solid, reliable protection that lasts longer than conventional greases. During periods of excessive pressure, increased heat and high shock loads, this grease resists breaking down and shields bearings from wear and tear.

Fortified with moly, for an extra layer of protection, Ultra Supreme Grease significantly reduces friction, which reduces wear and contact area temperature. This in turn leads to increased equipment life, less downtime and extended lubrication cycles. Ultra Supreme meets Caterpillar’s 5% moly specification for grease.

Ultra Supreme is one of our tackiest greases; it should not be used in passenger car automotive wheel bearings and electric motor bearings.

Performance benefits

• Resists emulsifying, washing out and spraying off when exposed to moisture.
• 100% reversibility; grease retains consistency during intense pressure and severe mechanical action. 
• Excellent shear and mechanical stability: grease stays in place, resists separating and running off components.
• Increased oxidation stability.
• Withstands pressures up to 500,000 psi while protecting against wear.
• High dropping point.
• Protects against rust and corrosion.
• Excellent pumpability and flowability in low temperatures.
