  • Wolverine Brass Compression Stops

    I was wondering if anyone here has had any trouble with Wolverine Brass 1/2" od quarter turn angle stops leaking. I have had five out of the last ten or so that I have used recently leak. They leak at the compression end and most times after tightening will continue to leak.Today I finally got upset enough and tried to wrap a little tefflon tape on the ferrul and use a bit of dope on the threads to maybe get a little more turn out of it. It still leaked. The ferrul never tightens up enough to crimp the copper tubing. I can usually pull the ferrul off.I did another test on a scrap piece of tubing. I took a new stop and tightened it until I was sure the compression nut would split to see if it would make a crimp on the tubing. It did but I was still able to spin the ferrul.I am about to stop ordering Wolverine valves. Any similar experiences?

    I never use them. Wolverine or any other brand for that matter. Compression fittings have a nasty habit of developing leaks over time.

        I hate em, we're plumbers so sweat a pipe. That said, our shop uses them almost exclusively, so I have no choice. Forget tape. Use teflon pipe dope on the ferril from the start and they seem to hold. At least on hard copper. If you're using them on soft copper I don't know.

          I always use pipe dope on the threads and a touch on the compression ring. I don't have experience with compression stops from W.B. Give them a call, I would be interested in how they handle it since we have just began installing W.B. products.

            I agree with the fact that comp fittings suck but I am in the same boat as someone else here, that is all our shop uses too.I switched them all out with Wolverine Brass multi turn stops which for some reason did not leak. I have never had a problem with Brasscraft stops.As for other Wolverine products, along with their comp stops, I hate their chrome p traps and tailpiece extensions as well. My old shop had a lot of problems with the cheap nuts cracking and the black washers leaking. We usually had to put a bunch of megalock in the slip joints.Actually the only Wolverine Brass product I like is their Hush ballcocks. I have put a few of their lav faucets in and dislike them as well. I'm a Delta guy.

              Even though I don't use them, maybe you just need to lean into the wrenches a bit harder.

                You gotta put the dope on the copper pipe after sliding the nut and ferrule on.

                Guaranteed not to leak.

                    I've never had a problem with them. What kind do you prefer? The solder or the FIP type?

                        You should never apply tape or thread sealant to compression or flare fittings.

                          A drop or two of machine oil on the threads is recommended by the manufacturer.

                            put the dope on the pipe, right in front of the ferrule.

                            when the ferrule tightens up, this makes sure the ferrule does it's job.

                              To you guys who use the compression stops exclusively, what do you use in applications such as under w/c's and pedestals where they are exposed? do they have extension tubes to "clean" them up I exclusively use the brasscraft sweat angle stops for pretty much all applications and have never ventured to try something else, but i dont think i would have my guys install these.
