What's the best pipe dope to use with black pipe. I've used both Hercules "real-tuff" and "blue block" with the pipes seated in the fittings tight and a little more than snug and I still get leaks. What am I wrong?

The green stuff by jomar is a great product. I have much better luck with using tape and dope.0
Pipe dope and tape, I'll try anything once or twice.0
It pays to wander off the Wall.Retired and loving it.0
That being read, I see i'm not alone in dope HELL, thanks keep them comming.0
by rector seal has worked great for us on 4" and under0
what is going through this pipe and what size is it ?0
1.5" black pipe it's boiler loop for a radiant system. Nothing special just a simple heating system.0
blu-block is good for gas...
and i never had a leak with it since we are only dealing with inches of pressure, but for water (and i usually test to supply line pressure) - use Teflon paste AND tape - keep soap spray bottle handy to spray before screwing in so that the Teflon doesnt just tare up immediately - i also use Teflon paste on those copper unions (thread and seats) why should i need to lock it so tight that you cant get it apart or have to wait until the minerals in the water seal it - douse it with Teflon paste - snug it - clean up with a rag (with acetone if needed, which also works on blu-block) - and have a nice day0
