Perfect lubricant for potable water situations. Used it on the o-rings and fittings for a pressure washer since the quick disconnect fittings were starting to become harder to insert or remove. Everything is operating smoothly now.

I used on my Flair Espresso machine o rings and it worked. It’s enough in the tube for a lifetime times 10.

Bought this to lubricate / protect the fire hose fittings on our fire truck. Works perfect, reminds of the Silicon lubricant we used back in my on ship Navy days to protect the fire hose gaskets on the ship.

I use this for my whole-house water filtration system, my hot tub plumbing, and my pool plumbing. It's food safe, and it keeps all of the gaskets and union fittings in great shape. It's easier to work with in a tube rather than a tub, although it's a little more expensive in the tube. 1 tube will last me about 4-5 years of normal seasonal tasks.

This is a specialty product designed to mitigate water, and corrosive damage for gaskets and other sensitive seals. I personally have used it to overhaul several aging coffee machines, such as my 1967 La Pavoni, and was amazed at the results at bringing my machine back to life. I also began using it on metal surfaces with contact rubber, such as the base for the classic Euorpiccolo models, as mentioned above and it has stopped any developed of rust in a traditionally vulnerable location. This product has numerous uses beyond what was mentioned and is well worth the money.

I have a water purification system that requires filter changeout evert 18 months. The system began to leak after the last changeout and I needed something that was both safe and would allow future changeouts. This stuff was perfect! A little pricey but worth it not to have to spend any more time under the sink!

If you're looking to grease O-rings this is the best lube you can find.Moen cartridges work better than new when given a few dabs of this grease.Also very effective in sealing water leaks in all manner of mechanical devices, and valves.Hose reel leaks are easily sealed using this thick paste.
