Plumbing: Compression Ferrule Removal Tools

i'm looking for a new compression ferrule remover. for those that don't know, you use it to remove ferrules (and nuts) from compression fittings seized onto copper pipe (typically 1/2") if you're replacing a supply valve or whatever. i thought i'd share the nicer ones i've found and ask you guys what you use.



Husky: Faucet Handle and Sleeve Puller
$13

i actually have this tool. it gets the job done, but it's a *************. i've pulled many ferrules with it, and i wish i got a nicer tool from the start.

it's hard to keep the arms from slipping off of the back of the compression nut. gripping it can be very fatiguing, especially in tight spaces or if you have to do several of them in a row. also, it's finicky to get the tool adjusted correctly. there are two parts that thread onto the rod, and they need to be appropriately spaced or else you either run out of room to turn or you can't grab the nut. it takes some trial and error, and it can be annoying to get it going.

ok, on to promising-looking upgrades:



Advanced Aquaduck: Duck Puller
$40-$60

looks to be of relatively high quality and is radially compact.

it's unusable without another tool to drive it, but you do have 3 options: screwdriver through a hole, wrench, or drill. i think they should have put a 1/4" hex shank on the end instead of round shank so you can grab it with a driver and not just a drill, but maybe they didn't want people using impact drivers on it, lol.



Saf-T-Kut: Brass Compression Ring Cutter
$50

this one is a bit different because it cuts the ferrule instead of pulling it off. i guess the ferrule is brittle enough that you can just snap it without actually damaging the copper pipe below.

it looks very longitudinally compact. the driving action is 90° to the pipe axis and is offset. it's hard to imagine every scenario, but this one might the best overall in terms of clearance issues.

that said, i've for sure been in situations though where this wouldn't work. sometimes the pipe stubout is very short, and the nut is practically against the wall. this tool requires the ferrule to be fully exposed. they kind of address that in the video above, but sometimes you don't have an escutcheon to remove to get extra space back. also, cutting the escutcheon off is a ****** solution.



Toolceptions: Ferrule Blaster
$75

looks pretty fast and easy to use. it's hard to beat not having to turn anything. i might get it even though it's expensive.

Nothing to add, but thank you for bringing these tools to my attention as I didn't know they existed. I've always used a hacksaw blade or a cutoff wheel on a dremel tool when I've needed to remove these in the past.

Nice tools but I usually don't have time to order one when needed. I hate to drop the coin and not have a use for it. Kind of a catch 22.

I've done a ton of bench plumbing with compression fittings and never thought the need for such a tool. Don't think they would work very well either but I might be wrong. $50 will buy you a lot of compression unions so what is your reasoning for such a tool.

I've seen this tool come up here before, and like you still don't understand it.

I suppose it could be used to replace a damaged nut or olive without shortening the line, but 1/4" compression is most often run with plenty of room to cut it back, and that's always the safer choice.

ime, pulling a ferrule is an effective technique.

the only time it hasn't worked well for me was when the last guy tightened the fitting down way too hard and actually deformed the pipe a little. it sucked because there was no room to cut it back / reposition the new fitting, and the fitting wouldn't seal 100% on that same spot on the pipe. the good news is it was a cabinet-less sink in my own house, so i just put bucket under it and kept an eye on it. it's in a visible spot in a well lit area. i lived with the slow drip (a drop per hour or two) for a month or so until mineral precipitation sealed it up. dumb maybe but still leak free today.

in my case, it has almost always been for replacing supply valves to sinks and toilets. i've done about a couple of houses' worth so far, and there was actually not enough room to cut it back for many of those. just unlucky i guess?

since removing the ferrule almost always works, i prefer to do that.

it's probably the same or less effort overall than cutting and deburring. if you can manage to pull it in just a few seconds (see the ferrule blaster video), then i think it would surely be less effort.

also, unless you have tons of pipe to work with (maybe if you're working with an exposed run instead of a stubout), it makes more sense to me to preserve those precious inches of pipe for future need where you actually need to cut it back.

Maun Industries in the UK makes a different style, which they refer to as “Olive Cutters”.
other UK tool brands make or sell something similar.
I think there only available in some metric dizes though.

Pasco: 4661 Compression Sleeve Puller
$25-$45
made in usa?

1624213312636.png

not sure if i like it as much as some of the others above, but i'd GLADLY take this as an upgrade over the faucet puller style (husky).
I have the Pasco. Only used it once, but it worked well and was worth the purchase price to me. Pulled the ferrule off easily. The replacement valve was/is leak-free.

UK uses a lot of compression fittings. I think it is because they do not allow open flame in many situations.

Hacksaw/file, screwdriver, and a tube of finesse.
I have the Husky, but don't use it. I just do one of the above. Works for me. My Dremel tool has gotten me out-of so-many jams over the years. Interesting to see all those different tools for the same mission.

Wow! You guys should all go and buy lottery tickets then! My house was built in 1977, and the ferrules are right up against the trim rings on every supply valve in the house. I don't even have a spare 1/4" to work with.

I didn't know about these tools until fairly recently myself, so in my house when I replaced the original valves with 1/4 turn ball valves, I reused the original ferrules and nuts. Boy did I have to tighten those nuts hard, and repeatedly, in order to get them to finally seal!

So there is definitely a need for such a tool.

There is not very many plumbing tool threads on garage journal. Thanks, pizza for starting an interesting thread.
