PFPE 501 is a chemically inert, high temperature vacuum grease, and extreme pressure lubricant.

With an upper operating temperature of 250°C and vapor pressure of 1.3 x 10-12 at 25°C, it is robust, versatile and can be used for sealing and lubricating under the most extreme operating conditions. This high temperature vacuum grease includes environments where aggressive chemicals and strong oxidizing agents are regularly used.
