    write up on Google search. It states that it will even seal a joint which is not fully seated due to positioning. I will have to check my local plumbing supply houses. Thanks for the reply Rich.

    I'm learning

    Anaerobic sealants are pretty amazing things.

    Lots of manufacturers, but not really common here other than industrial and fire sprinkler applications.

    Not a pro

    But I used Hercules Megaloc on all of my gas piping and it worked well.  I didn't use any tape as it seemed to be frowned upon.  So far that is the only dope I've found that I really like.

    Pipe sealant:

    Teflon Tape on everything. Now, only the Blue Monster stuff in the 1/2" x 1429" rolls. You don't loose them as easily. Rectorseal #5 on gas or any of the other kinds that you can't get off your tools or clothes or Rectorseal #100 with Virgin Teflon or MegLoc on potable water. Almost 100% leak proof.
    Heat is Teflon Tape with usually Rectorseal #5.

    I'll ask again

    Does anyone make 3/8" wide Teflon tape?  I'd love to have it for the small stuff.
