## Description

Flaring Tool 2 in1 Flaring & Swaging Tool

Review: Good Quality, Works Great, Well Made! FANTASTIC TOOL - FANTASTIC TOOL.... I needed a new flaring tool as my old one gave up on me and broke in the middle of a job of course, so i ordered this one quick from desertcart as i could have it quick enough to finish the job, local stores want crazy money for an eccentric flaring tool, i'm talking $200-300 for what looks like the exact same tool in a different color at my local home improvement stores, so i was skeptical that a $50 tool could do the job as well as them but my old one i have had for 20 years was in pieces so it was time to try a new one. Man this thing delivers! It looks like a very well made tool, and it is. The fit and finish on all the parts is nice, it slides together and works perfectly like it should, and it looks good doing it. This thing made a perfect flare on the very first try and every one after it looked just as good. Having used these type of flaring tools before the real trick to them is getting the stickout right, and this one has a little sliding stop gauge to take all the guesswork out of it, with my old one i knew roughly where you had to set the pipe end to get a good finish on the flare and be the right cone depth, this one does it for you, slide the stop over the size hole you are going to use, slide in the line until it touches, and then slide over and tighten the side screw and flare it, its so quick and easy with this thing a child could make perfect flares in seconds. Tips for good flares... debur! If you don't have a deburring tool get one, just deburring the end of the cut pipe makes a huge difference on getting a nice clean accurate flare because tubing cutters slightly roll in the end at the cut, you need to cut that back with a deburring tool. When you tighten down the tool making the flare go until the clutch mechanism disengages and spin it three additional times, it will click on each rotation, the clutch sets the final depth, the additional three turns allows the cone to burnish the copper surface and make it as smooth as possible for a good seal. Use a little refrigerant oil or Nylog on the cone of the flaring tool to lubricate it, this helps further smooth the final finish if you put a little drop on the cone before each use. I hope to get some years out of this one, but at this price, even a dozen installs and its paid for itself many times over and i can afford to replace it. That makes it a good value for the money! Some final words.... This is an eccentric flaring tool, i have seen reviews on these saying that the cone wasn't centered and they thought it was defective... Thats how they work, its literally in the name, eccentric.... The cone rotates in an eccentric path like a cam lobe to slowly push and stretch the copper outward to form the final shape. No storage case? Who cares... I put this in my packout case with all my HVAC gear, a storage case for it would just add bulk and weight i don't need, why are some people so nit picky, this is a $50 tool that replaces brand name ones going for $200-300!!
Review: Great flaring tool - This flaring tool works great for making perfect flares on copper tubing. It it sturdy and well built. The price is reasonable, and the eccentric forcing cone makes very nice, perfect flares on copper tubing. I have not used it on aluminum yet. I have used it on 1/4 and 3/8 . The flares were the perfect size and the clutch mechanism ensures you do not over crush the flare. The copper. insertion depth limiter ensures consistent insertion and the correct flare size without splitting the tube or making the flare too small. My previous flaring tool also would come completely apart. The clamp piece was separate from the top piece with the forcing cone. This one stays together as one assembly, but is easy to use. The indents and alignment marks make for proper alignment for flaring the tube. I highly recommend it.

## Features

- [Eccentric Type Cone] - The eccentrically mounting hardened steel flaring cone produces a rolling action for even metal flow, giving uniform flare walls without wear. Applicable tube outer diameter: Φ1/4 ", 5/16", 3/8 ", 1/2", 5/8 ", 3/4".(NOTE: It will only do single flare - not double flare!)
- [Limit Piece & Clutch] - (1)After inserting the copper tube, the length of the flared tube can be precisely limited by the limit piece, which is more efficient and convenient than measuring by eyes only. (2)There is a clutch in the rotating handle, which will automatically disconnect when the flaring operation is completed.
- [Ultralight] - The tubing flaring tool is made of aluminum alloy and is very light. It's less than 1kg, so you can hold it and work for a long time without getting tired.
- [Wide Application] - The tube flaring tool is applicable to soft metal tubes such as copper tubes / aluminum tubes. Widely used in electrical products, like HVAC, air conditioners, air heaters, refrigerators, etc.
- [Packing List] - This flare tool includes the gantry * 1, inch-type flaring clamp * 1 (without a case).
