Comments about ACE HARDWARE Ace 1/2in IPS Pipe Repair Clamp:

I bought the 1/2" ACE pipe clmap as well as the 3/4" version to have ready in case of a pin-hole leak in my copper pipe. When I had need to use it, it was very difficult to open (the hinge was very stiff). I had to stick an old chisel in there and turn it to spread it open.

When closed, the square holes didn't line up properly, which is a problem, since the square part of each carriage bolt is supposed to fit in both holes. I had to bend it into shape with a variety of tools. This was a manufacturing issue of the one I had (my 3/4" version also had this problem). Of course, the one in the website picture is perfect.

This item comes with a thin piece of foam rubber that acts as a gasket for sealing. Unfortunately, this didn't work very well, so I took the foam rubber from the 3/4" onee I bought and put both in there to see if that would seal it better. It did not and still leaked. I believe it was ill-advised to provide pieces of foam rubber, since the foam rubber was porous and when saturated, it dripped out of the end (I had it on a vertical pipe--it dripped out of the bottom).

So, I went to a different hardware store where I knew I could get a piece of vinyl tubing to replace the foam rubber gasket. I got a piece that was 1 1/4" in diameter with a wall thickness of 1/8". I then cut it open and sized a piece for this clamp and reinstalled. This worked perfectly with no drips.

When installing this, you may find it useful to use a pair of pliers to squeeze it closed while trying to put the nuts on. So you can make sure that the square parts of the carriage bolts fit properly through each square hole when you tighten it up.

If the clamp hole had lined up properly (like the website photo), if they had included a piece of 1/8" thick vinyl (which is non-porous) instead of the foam rubber, and if the hinges weren't so tight (very hard to move), I would have given this item 5 stars. But, cause it's not that good out of the package and leaks with the foam rubber, I'd have to say that, unmodified, it's not very good and only gets 2 stars.
