I am installing a clawfoot tub..... the drain pipe and overflow connecting to the tub drain foot and overflow fixture are not the conventional compression type seal but a really fine thread only about 6 full threads.

The threads I assume need a sealing compound not teflon tape? What sealing compound do I need to apply?? or is recommended??

Thanks..... Msquared

I usually use regular pipe joint compound.

Thank you...I'll give it a try

in the old days, i worked for a shop that had a policy of soldering that connection. of course the tee and tailpiece were rough brass and going to be concealed. so we used flux on the threads, turned the tee upside and ran a bead of 50/50 solder.
i'm not advocating soldering that joint, just telling a story about the old days.
since the likelyhood of that connection ever having to be taken apart is about zero, i wipe the excess 100% silicone off the tub flange connection and apply it to those fine threads.
