Tek-702 is a silicone diffusion pump fluid designed for fast pumpdown of large volumes of gas or vapor in large vacuum chambers. It resists oxidation at high temperatures and is temperature stable to insure system cleanliness and redude maintenance. Typical applications include : Vacuum heat treating and vacuum melting. 1 gallon.
Tek-704 is a silicone diffusion pump fluid which provides greater ultimate vapor pressure capability than Tek-702. It also exhibits lower backstreaming rates than Tek-702. Typical applications include : Vacuum heat treating, vacuum melting, vacuum metallizing, vacuum coating, space simulation chambers and research.
Tek-705 is a silicone diffusion pump fluid designed for ultra-high vacuum applications such as optical coating and space simulation. This type of silicone exhibits the lowest ultimate pressures and up to 100 times lower backstreaming rates compared to 704 silicone.
