Danco 80360 Waterproof Faucet Grease, 1/2 Oz

I use this product for multiple applications including my faucets, a positemp valve, and on o-rings in my water softener. What I like is that it’s rated as “food grade” and NSF 61 certified. You can use it on plumbing that makes potable water. It doesn’t break down quickly like a lot of other products. Even after a few years on the positemp valve, my shower faucet handle turns smoothly just like when I bought my new house. You can’t beat the price at under $4. It’s a decent size too and more than adequate for multiple jobs.

great product

Great product, worked well.

Worked fine for the shower handle cartridge I installed.

If you are ever doing faucet cartridge replacement or O-ring replacement, always have some of this on hand. I know people use petroleum jelly, but it's not the same. This is silicone based whereas the jelly is petroleum based which can actually degrade seals and rings. Small tube of grease, but unless you're repairing faucets on a daily basis, this will last for years. Good stuff!

Works great for a good price, thank you

I use this for o rings on my two water catchment filter canisters every time I change them. Works awesome.

I had to fix the water return pump on my Whirlpool dishwasher. The appliance repair guy on the YouTube video recommended using this to make the pump gasket watertight and prevent leaks. It's holding so far. Easy to use. Very inexpensive way to prevent water damage to subflooring. YouTube saved me from buying a new $250 pump or $600 for a new dishwasher. A long gray hair was jamming the pump mechanism.
