HAUTMEC Internal Pipe Wrench Set, 3/8-inch, ½-inch, ¾-inch Easy Internal Grip Extractor On Pipe Nipples, Steel Construction PL0031

This tool worked perfectly. Saved me money!

this product worked great for me to remove a broken pipe nipple for my shower

The cams don’t engage correctly to grip the inside of the pipe. Returning this piece of garbage 👎🏽 get a proper nipple extractor, save yourself the time and money that I’ve wasted on this cheap crap

Very helpful item

To work properly, the only real requirement for eccentric style of internal pipe wrenches to have serrations sharp enough to grip the inside of the nipple. These work well enough on brass, but think harder materials would be a challenge. Fortunately, my nipples were horizontal so I could use the hanging weight of the free lobe to help get the initial grip side the nipple. If the application needed to be vertical, it would have been a challenge because the serrations would have had a hard time catching the pipe material. But face it, the eccentric style is the cheapest possible internal wrench, and these are the cheapest of the cheap. They would be frustrating if used on a regular basis, but for occasional use they work good enough.

Great tool to have, easy to use, I tried multiple different kinds of tools, but this one worked great

This is my first time using one of these so maybe it's not suppose to, but this did not work for me because once the wrench reaches maximum width, it doesn't lock - it'll keep spinning and eventually get smaller again. This sucks because the thing I'm trying to remove is really stuck in there, and even though the wrench grabbed the inner wall of the pipe, the rotating piece just kept rotating in place and it got smaller again.
