Default How do you guys seal your threads?

Just curious on what product you guys use when assembling fittings? There is a few different way to do it and I was at my local supply house today when the question came so i was just curious.

Blue Monster tape and RectorSeal #5. On my day job, when I run gas, I just use the pipe dope they supply, which is Oatey Blue Magic, since they don't want to buy gas rated tape.

Do you use tape and #5 at the same time and if so why? Just curious.

I thought that the Members of this Forum / US & Canadian Plumbers / Pipe Fitters adhered to the `Theory` that threaded Joints do NOT require any Jointing Compound / Sealant etc. - ?

I have had arguments about that point on here - as it is obvious that threaded joints DO require Jointing Compound / Tape or other forms of Sealing the Joints.

When I was `arguing` this point I do not recall any `support` for what I was stating - I.E: that the Joints must be Sealed.

Although I was primarily arguing this point in relation to Mild Steel / Black Iron Pipe - tapered threaded joints of almost every kind require sealing.


I see now that Members DO use Jointing Compound / Teflon Tape on their threaded joints !

Well in school here Canada they claim Teflon and dope only lubricate and not seal the joint, I don't believe it myself but that's what they teach us. I think theoretically you don't need either considering they only lubricate the threads to make it easier to get more turns on your pipe to seal the connection, the taper is what makes the seal. Not saying I agree with that totally or believe it entirely. I think it would be pretty dumb to just throw together some threaded connections without tape or dope, hell I do both in almost all cases.

The disagreement was that it's the tapered threads that seal the joint not the joint compound. If the joint compound did all the sealing there would be no need for tapered threads. If they were running threads no joint compound could make the joint water or gas tight.

I didn't start this thread as a debate as to why or why not sealant/lube should or should not be used but was just curious on what others used, whether you do or do not need to use it we all do for one reason or another.

When those of you that use tape and dope use it, do you tape first or after the dope?
