    I have ancient bathtub on the second floor where the drain was leaking so i replaced the crap there with pvc the only trouble there is a 90 degree connector that connects directly to the tub and it has a thin brass pipe that srews directly into it .....the threads are very very fine as well as short....(about 3/16 to 1/4 inch long) i doped it up and tightened it all the way and i am getting a small drip .....i did notice when i took it off it has some hardened plastic blue stuff around it.....was this plumbers epoxy?

    should i put some of this plumbers epoxy around the joint to seal it off?

    thanx

    also very stupid question here.....do u guys tape compression threads on drain stuff (pvc or brass or even that chrome) before tightening?

    If by "plumbers epoxy" you mean pipe dope, that is a very common item to use on threaded connections...
    You should use it or teflon tape when making up a joint where the threads seal...
    As for compression joints...
    The teflon tape will hinder your tightening them... It is not the thread that seals the joint on a compression fitting...
    It is the ferrule on the pipe that forms the seal between the pipe OD and the fitting - the threads simply allow you to apply force...
    A bit (very little bit) of non-hardening pipe thread sealant (lubricant) might help in the tightening... It will not help with sealing....

    The blue stuff might have been thread locking compound. Try some pipe dope.
