The ULVOIL Z series is high vacuum fluorine grease that uses fluorine-based synthetic oil as the base oil and adds PTFE (thickener) to exhibit good lubrication characteristics even in the special environment of vacuum. High-performance solid lubricants are carefully selected and blended, and by using low vapor pressure oil as the base oil, this series can maximize the lubrication characteristics as well as to minimize the pollution of the vacuum environment.

To maximize the lubrication characteristics of the Z series, avoid mixing with other substances.
Please pay attention to the following points when using.
1.Keep the parts clean.
2.Please use clean equipment for filling.
3.Keep it clean so that dust does not get inside the grease container.
