Dow Corning High Vacuum Grease Lubricant 1/2 oz

Using it to seal glass tubing to a flat Viton gasket on a stainless steel base. Running at 2.6E-6 Torr without issues. Great product!

Smaller than expected but works as it should. High quality thick grease

As other posters state, a little bit is all you need. Using to refurbish aged GM Climate Control units with vacuum manifolds. This stuff gets everything flexible, sealed up properly and working again. Use in a very clean environment and be prepared for good results.

Volume smaller, price higher, product still just fine. WDM

Excellent price for small quantity. A little goes a long way and for infrequent users, this is a good value to avoid excess product never being used at much higher cost.

Great product!

Do not buy this; it was repackaged with some inkjet sticker.

Good grease, nice small amount
