Description

SCHAEFFER’S (since 1839) – 238 Ultra Supreme Waterproof Grease is a premium, multi-purpose aluminum complex grease specifically engineered to provide superior protection and performance in the most demanding heavy-duty automotive and off-road applications. Formulated with severely hydrotreated polyalphaolefin (PAO) synthetic base oils and severely hydro-finished 100% paraffin base stocks, Ultra Supreme delivers unmatched durability and resistance to extreme conditions, making it ideal for high-pressure environments, increased heat, and heavy shock loads.

Ultra Supreme grease quickly adheres to metal surfaces, offering long-lasting, reliable protection that outperforms conventional greases. The unique formulation resists breakdown under intense pressure, heat, and shock, shielding bearings and other vital components from wear and tear. Infused with molybdenum disulfide (moly), it provides an additional layer of protection by reducing friction, which helps lower wear and contact area temperatures. This leads to extended equipment life, minimized downtime, and longer lubrication intervals.

Meeting Caterpillar’s 5% moly specification for grease, Ultra Supreme is designed to withstand pressures of up to 500,000 psi while continuing to protect against wear. Its high dropping point ensures it remains effective in high-temperature operations, and it offers excellent resistance to rust and corrosion. Additionally, Ultra Supreme’s exceptional shear and mechanical stability ensures that it stays in place, even under extreme pressure, preventing separation and runoff.

While it offers outstanding protection in harsh conditions, Ultra Supreme is not recommended for use in passenger car automotive wheel bearings or electric motor bearings. This grease is highly tacky, making it ideal for heavy-duty applications where cleanliness is essential. Distributed worldwide by Miken Electronics, Ultra Supreme Waterproof Grease provides the ultimate protection and reliability for your equipment in the toughest environments.
