DUOYI Olive Remover Puller Tool - Yellow Solid Brass - 9cm x 7.8cm

Project: Removed two twenty-year-old shutoff values (hot & cold), which also required removing each shutoff values’ brass compression ring from copper water pipes that are 1/2” inside diameter (5/8” outside diameter). The brass compression ring is normally difficult, if not impossible, to slide off of the pipe without a specialized tool (you can check internet for various methods for removing brass compression rings). So did this tool work? Short Answer: Yes; the tool worked. It removed (slid) the brass compression ring off of each pipe. Long Answer: Overall, the tool appears to be well made (feels solid in the hand, well machined, handle & threads move freely without sticking or jamming). Tool description on Amazon says that the tool is “… suitable for brass pipes with diameters of NPT 1/2” & NPT 3/4” …” My project involved 1/2” inside diameter (5/8” outside diameter) copper pipe and it fit perfectly with the tool’s 1/2” fitting. I did not have the opportunity to test the tool’s 3/4” fitting. It took a minute to figure out how best to use the tool (an instructional video I found for a similar tool helped). This tool is not complicated, but if you’ve never used a particular tool before it always helps to see it in action to demystify how best to use it. Note to vendor, a short/simple instructional video with tips would be a nice addition. The handle that comes with the tool worked well to get things started (e.g., seating the tool’s threads into the threads of the shutoff valve’s compression nut and then working the compression ring off the copper pipe a bit), but once the compression ring reached a certain point on the pipe it became difficult to turn the tool’s handle (was hard to get the leverage / torque needed to keep things moving). Per another reviewer’s suggestion I removed the included handle and used a short screw driver as a handle (I used a Torx screwdriver, but a Phillips head would have worked just as well). It gave me the leverage I needed to keep turning the tool to move the compression ring along the pipe until it popped off. There was no damage or deformity in the pipes afterwards. Good tool and recommend. Would be great with a better handle and perhaps the option to seat it in a power drill.

Easily removes stuck ferrules (olives in some areas) from pipes to replace or remove compression fittings. simple and fast to use. Solid brass construction to and built to last.

Works great, made very well, fits nice, versatile for 1/2 and 3/4.

Tool worked beautifully!

I bought another model first, and it didn't fit the pipe correctly and was too long to work in tight spaces. I then returned that model and replaced it with this one. This one worked beautifully! It fit the pipe correctly and its small size made it easier to work with. I was able to remove the Olive in minutes. This is great value if you need to replace under the sink stoppers and don't want to call the Plummer. I also find it well made, should last a lifetime.
