Review: GREAT STUFF - This is my second jar of Dow Corning High Vacuum Grease Lubricant. It is very thick, which I need from time to time. My first jar lasted 5 years. It is great for lubricating various pool gaskets, such as my pool filter housing lid. It may be a little pricey, but if you need a thick waterproof grease, this is it! For me, much better than the really thin "watery" lubricating grease. Buy with confidence.
Review: Excellent product, fast shipping - Although this product is sold as a high vacuum grease, I use it to seal the rim of my modified paint pot used for a resin pressure pot. Excellent results.

## Questions & Answers

**Q: does it wash off with soap and hot water ? or how do you remove it once used ?**
A: We fill these on site.  We wipe the counter with lint-free wipes beforehand and cloth followed by paper towels afterward.  Any remaining residue w'll remove with isopropyl alcohol.  Avoid using any degreasers as it is not known how the components of any given degreaser will react with with the components beyond the silicone base.Here is the SDS for reference:http://www.dowcorning.com/DataFiles/09027701837b0cf5.pdf

**Q: Will this work to prevent vacuum leaks in an automobile engine ?**
A: No I don't think so  , automobile engine is pulling/ pushing stronger.

**Q: Is this grease plastic safe? will not deteriorate plastic?**
A: I can't answer over the long term, but I have used this grease on plastic fittings, plastic containers, black and red gaskets, and other items. I haven't seen any degradation of these over the last year or so.

Normally incompatible grease will either dissolve the material or cause gaskets to begin cracking. I have never seen any deformation or stains indicating plastic dissolving, and I have used the same gaskets multiple times with no cracks or breaks.

When I need a refill, which could be years from now since it seems to last forever, I would certainly buy this again.

The best I can do is give you my experiences, but in this case I think you are good.

**Q: Can you use this on fittings for residential hvac systems? i.e. gauge/unit connecting hoses and micron gauge?**
A: I'm no expert in HVAC, but it's mostly silicone based, so very unreactive, but avoid other silicone.

Although this product is sold as a high vacuum grease, I use it to seal the rim of my modified paint pot used for a resin pressure pot. Excellent results.

### ⭐⭐⭐⭐⭐ The right stuff.
*by J***F on June 22, 2019*

Seems to be the real stuff. Really thick and sticky. Just like I wanted. Container was nice and full. A tube is cheaper but I’d have to pass it on to many future generations. Very useful as a non-separating damping grease.
