Specification Brand : Midwest Tungsten Service BulletPoint1 : Reliable and Safe:The oil is packaged in a safe and convenient gallon size to reduce the likelihood of spills or leaks during transport. It's crucial to carefully follow the instructions on the MSDS sheet and take proper safety measures when handling BulletPoint2 : Vacuum production : Vaccum pump oil is EQUIVALENT to Dow Corning DC-704 diffusion pump oil for use in high vacuum production environments BulletPoint3 : Durability and Efficiency: Ideal for challenging and demanding applications, with a quick pumpdown feature that efficiently removes gas molecules from the vacuum chamber. It remains the industry standard for various industrial processes such as brazing/soldering, E-Beam welding, and large-area coating, ensuring reliable and efficient performance. BulletPoint4 : "Formulation: Diffusion pump oil is formulated with mixed phenylmethyl dimethyl cyclosiloxane (Tetramethyl tetraphenyl trisiloxane.) used only as a diffusion pumping oil. BulletPoint5 : Enhanced Oil Durability: The oil's exceptional resistance to hydrolysis and oxidation means it stays in top condition for longer periods, delivering consistent high performance and reducing the need for frequent maintenance.

Midwest Tungsten has filled the gap by offering private label 702 chemically equivalent products in gallon bottles. MT-702 diffusion pump fluid is a general purpose fluid designed for fast pumping of large volumes of gas. It is used to produce vacuums in the range of 10E-5 to 10E-7 torr. It is also used in vapor ejector pumps that attain vacuum of 10E-4 to 10E-5 torr. Replacement for and equivalent to Dow Corning DC-702. Sold as DS-702 and Invoil 702 elsewhere. ProductSiteLaunchDate : 2015-05-20T07:00:00.000Z RecommendedUsesForProduct : ALTEMP Q NB 50 can be used for the assembly of frictional connections, e.g. annular springs or split taper sleeves, and positive connections, e.g. bearing seats, profiled guides, etc. The product has proven particularly successful in the lubrication of clamping chucks. High precision and constant clamping forces are essential requirements in chucks. Any decrease of the clamping force may cause tools or workpieces to become loose. ALTEMP Q NB 50 improves the sliding behavior of moving chuck components, enables constant clamping forces and may therefore be used in all types of chucks, such as scroll, cam and spiral chucks. It prevents stick-slip and protects against tribo- and fretting corrosion in frictional or positive connections. Furthermore, ALTEMP Q NB 50 is resistant to water and media, e.g. against cooling lubricants.
