Customer Questions & Answers

Is it only good for Black Pipe natural gas fitting or we can also use on brass fitting like gas valve etc?So we can disassemble easily for next time?

Asked by: Homeowner
you can use Block on black pipe and brass for natural gas. This thread sealant (like all of ours) are non-hardening so you can always undo the fitting at a later time without an issue.

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 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 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 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.
