Superior Tool Company 03943 Compression Sleeve Puller and Sleeve Remover for 1/2-Inch Compression Fittings Only

Exceeded expectations. Worked every time for pulling ferrules from 4 copper stubouts with no pipe damage.

I wanted to replace the compression valves in our bathroom with all oil rubbed bronze hardware and it was simply too expensive to have a plumber do it. I spent a lot of time on some DIY forums and was mostly told not to mess around with this stuff but I am glad I did.It was trivial pulling the old compression valves off our copper plumbing lines. You simply screw the threaded end of the device into the existing nut and then turn the handle until the brass or copper or whatever the compression ring is made of slides off. I used fine sandpaper to cleanup the pipe and slide the new ones on.I had my wife turn the main water supply line back on one-half turn at a time. One of my valves was leak free and one had a very minor drip which I easily resolved by turning the nut 1/4 turn until it stopped.This is a very nice quality tool for dirt cheap. Don’t be afraid to do the work yourself—it’s easy and you can do it! Just watch a few videos first and you should be all set.Good luck!

For the price, this tool works well, and should be fine for the ameteur plumber if there's enough room to use the tool. If you can spend more, and think you'll be using it a lot, I'd shell out more money and get a better tool. One tip for those finding it difficult to crank - use two wrenches to get it started: Tighten the nut on the barrel of the tool a few turns, but not all the way. Now tighten the crank down by hand until it gets hard to turn. Then put a wrench on the body of the tool, and another on the nut, and start "tightening" the nut onto the tool with the wrenches which provide better leverage. Once it starts moving, the crank will turn easier. The only big down side to this tool is that it may not fit in tight quarters, or if the pipe is coming out of the floor, but too close to the wall to crank. I agree with another reviewer that it would be even better if the top of the crank had a hex shape we could put a wrench on for better leverage (like the Pasco 4661 or the Lasco 13-2708).

Unlike other reviewed tools of similar design that aren't made for American fittings (watch out for any product that calls a ferrule an "olive", like they do in the UK) the diameter and thread pitch of this puller will fully engage any 1/2" compression fitting sold by a typical USA hardware store like Home Depot. Some removers that slip behind the nut don't work as well because: 1) If you have a short stub out (extending barely beyond the wall or escutcheon), you might not have enough clearance, 2) The traction force applied to slide the ferrule off is not completely centered over the pipe, making it less efficient and increasing the chance of deforming it (yes, it happened to me when using a tool of that design!), 3) Once screwed in place, the puller won't slip off the pipe while tightening, allowing easier removal with one hand. Especially in case the previous installer over tightened the fitting, as a precaution I spray a penetrating lubricant on the ferrule (like liquid wrench), and let it sit for a few minutes before slowly turning the crossbar on the puller to help it slide off.

I’ve used the bearing puller type all my life and it works great. Was looking at getting another one and saw this kizmo. I was like, why not. First time trying it I had to ream the inside of the copper pipe about 3 seconds to get it to fit better. After that it worked like a charm. Money well spent. Just wish I had invented this instead.

I was about to tackle the task of changing 6 shut off valves and watched numerous YouTube videos to see what tools I needed or what issues I might come across. I’m a 42 year old female who has never had any kind of plumbing experience other than changing shower heads.After seeing there would be a compression sleeve that would be a little difficult to remove without a tool, I decided to buy this one (per recommendation from one of the videos I watched) even before I started. I was looking for something that would make it easy to remove without have to try to be careful and cut into it because I just KNOW I’d screw it up somehow.This tool did the trick! Super easy to use. The compression sleeve came off with ease. After sweating, huffing and puffing to remove the 25 year old rusted valves, this part of the process was the easiest. Just slip the tool into the pipe, screw the nut onto it and twist it off.I was also changing out my whole sink so I feel I gave myself more space to work with, but it still had plenty of room to do the job. Just be sure the pipe is 1/2” as it will only work for that size!Overall I’m super happy with this tool and feel it really helped me finish my project faster than I would have without it. I don’t think I’ll be needing it anytime in the future, but I’m glad I’ll have it in my toolbox ready for the next time I need to use it!

I am not a plumber. That said, one always needs to replace shut off valves from time to time because they fail from not being "exercised". Apparently you should turn them on and off once a month, but no on really does this and there is always the risk of stirring up a leak where there was none. This device is built for 1/2 inch copper to pull a ferrule (olive in England) which can be difficult to get off without screwing up the copper pipe. You can try and reuse the one that is in place, but in my limited experience it is better to just replace them with a fresh ferrule. This tool is awesome and brilliant at the same time Just buy one one if you even plan on doing even one replacement. There is always a chance that the copper pipe has been deformed by over tightening, but if this has not occurred then this tool will remove the ferrule without damage. Still I would freshen up the copper with some very fine sand paper to just make it clean again. Don't over tighten. If it leaks then tighten gradually. There is nothing more satisfying than having the right tool for the right job. This thing defines that situation.
