Forum Title: Silicone grease
Probably answered before, but search yielded nothing. Should I use silicone grease when replacing a diverter valve? Apply to the o-rings and a small amount on the threads to lube? Is it generally a good practice to use silicone grease on o-rings and faucet washers too? Finally, what is the difference between silicone grease and waterproof grease? Both come in similar looking containers but are clearly named differently. Thanks,

neoprene washers and o-rings are oil based. most stem grease is oil based. silicone is not oil based. A lot of products today are made of plastic. You should not use oil based grease or thread paste on plastic. You will see warning sign on a lot of oil based thread sealants DO NOT Use on Plastic Fittings So that said. Use your best judgment. I'm guessing the silicone cost a bit more.
