Thermalle™ VACUSEAL Silicone-Free High Vacuum Grease

Thermalle™ VACUSEAL Silicone-Free High Vacuum Grease is a high-quality, non-toxic lubricant formulated specifically for use in vacuum systems. It is a good general purpose hydrocarbon grease that contains microparticles of PTFE and is compatible with most metal, plastic, and elastomer system components, being free of silicone, halogens, and heavy metals.

VACUSEAL provides needed lubrication and sealing of o-rings, gaskets, and valves, and is resistant to oxidation and thermal degradation at temperatures below 30°C.

Note: Due to its hydrocarbon content, VACUSEAL is not compatible with rubber, PVC, EPDM, and EPR seals.

NOTE: VACUSEAL is NOT recommended for any product that may warm to or exceed 30°C. For applications with higher temperatures, it is recommended to use VACUSEAL PLUS, a silicone-based high vacuum grease for temperatures up to 260°C (Part No. CT-TM012 – Available in all sizes mentioned above).
