I use tape where I might need to remove later on. As long as you don't clog anything with too much dope I don't see any reason not to use it for that. I wouldn't use dope on anything that might have contact with water such as a pressure guage on a filter or something like that. That's mostly because I don't want to take a chance on anything in the dope being toxic. I'm sure there are nontoxic nonwatersoluble dopes out there.

Okay, You Try Doing This Stuff While Stupid!


Hi,

I prefer pipe dope, though I doubt any real difference, just with pipe dope I “feel”:rolleyes: as though I am getting even coverage:eek:, stupid probably but I always imagine (?) I am leaving gaps with Teflon tape.:eek:


Plumber’s Pipe dope will not (should not?) pose any risk; I have used the stuff for many years.:)

Biollante's probably got the right stuff. I always end up finding the stuff for cast iron pipes and heating applications. I'm pretty sure you don't want to use that on aquariums but I haven't checked.

Application

Hi,



I suspect the main thing to look for is the application, while getting the appropriate dope for the materials.:)

I use teflon tape on all my connections for a more permanent fix. If bubble counter fluid or mineral oil come into contact with non-hardening thread sealer, it can cause leaks. Plus for higher pressure situations like CGA connections, teflon is a sure bet.

needle valve and bubble counter has dope from before and has not leak so I left it alone .
