8-12-2009 My bathroom tub faucet was leaking and water was coming out the back of the tub spout. I fixed the leak in the faucet then went to remove the spout to make sure water was not going behind the the wall, it was not, but as I was putting the spout back on the plastic thingy broke and of course there was no universal replacement part. So I needed to cut the pipe for a new spout. I found these shark couplings that worked wonderfully and give you a waterproof seal without sodering, if you have a clean square cut.
