Is this sealer safe to use on fittings supplying potable water in the house?

I have used this sealer before on oil tank fill lines, it works great! I am installing a whole house water filter that has NPT threads and I do not like the way the fittings bottom out in the housing before tightening up, even with a good amount of teflon tape on the threads. I figure this sealer would do the trick but need to know if it is safe to use...and if not what would be a good sealer to use other than just teflon tape.
Asked by: Homeowner
No. use teflon paste or pro dope, or you can just use teflon.

8 oz. Block Pipe Joint and Gasket Sealing Compound is rated 5.0 out of 5 by 4.
Rated 5 out of 5 by from Great pipe sealant Have used this on threads for 60 psi steam, condensate, ethylene glycol piping system and 185 deg F hot water heating 3-inch pump discharge. All without problems. I like the consistency and ability to spread in various ambient temperatures.

Rated 5 out of 5 by from works amazingly well I was working on a habitat for humanity site with a plumber from Roto-Rooter. we used a different thread sealer that did not get into the threads at all after pressurizing the system it was leaking like a sieve. we decided to clean off all of the threads and replace the thread sealer with blue block after that we had no leaks.

Rated 5 out of 5 by from Works great! There is nothings like knowing that all the work you're doing is going to hold. No having to have 3 different types of sealants around my house for different applications is a great idea. This sealant does it all! Gas, water, air won't go pass this bottle.

Rated 5 out of 5 by from Great! I use this all over the place. Threads on drain slip joints, threads between copper and brass. Works great. For threads between copper and brass I put two wraps of teflon followed by a generous brush of this. Never had a joint leak after that.
