Tri-Flow Clear Synthetic Grease forms a tough durable film of lubrication to prevent metal-on-metal wear. It is far superior compared to petroleum and white oil based greases that are on the market today. The pure synthetic based formula features outstanding performance in high temperature applications (-10 to 400 degree Fahrenheit). The waterproof formula resists oxidation, rust and corrosion and provides an excellent seal on high-load carrying capacity bearings.
