Dow Corning High Vacuum Grease is used as a sealant and lubricant in a variety of general laboratory applications. Some of these applications are as an anti-seize sealant in ground glass joints, a lubricant for stopcocks and valves, a lubricant for gaskets and O-rings, and a sealant in vacuum and pressure systems. This high vacuum grease is suitable for high temperature applications up to 400° F. In particular, we recommend it as a joint sealant with our ground glass joint glassware products. You get a tube of 150 g (5.3 ounces).
Dow Corning High Vacuum Grease is a stiff, non-melting silicone lubricating material that is stable over a temperature range from -40°F to 400°F (-40°C to 200°C). It is chemically resistant to mineral oils, many common gases, dilute acids and alkalis, and aqueous solutions of inorganic salts. For many years this product was called Dow Corning 976 or 976V High Vacuum Grease.
