Rated 1 out of 5 by Line slips in the die I recently got this tool to repair the 3/16 brake lines, and 1/4 and 5/16 fuel lines on my honda civic. It did the 3/16 line well, but when attempting the first part of the double flare on the larger sizes the line slips out of the die when tightening the yoke. The holes in the die seem to be too big to hold the line, I even tried to put the die in a bench vice and it STILL slipped. After being completely frustrated a friend of mine brought over a tradition style flaring tool from one of the big name tool companies and it flared the lines first try. When comparing the two dies it was clear that on the Ridgid tool the holes are considerably larger. I am very disappointed that this tool did not work since I specially ordered it from the internet because I could not find it locally. Now I'm out the money and I still need to buy a tool that can probably do this type of work in the future. August 30, 2015
Rated 1 out of 5 by below expectation After buying what i thought was decent quality double flare tool to do mainly 3/16 automotive brake lines i am let down . the dies don't properly align and and it always pinches one side and the flares don't come out en even. At close inspection its plane to see there is an uneven step in the die on the chamfered edge. May 1, 2015
Rated 5 out of 5 by Superb tool for the job I needed a high quality flaring tool for install of Ductless mini-split heating/cooling system. I looked around at all the major brands and even some of the generic brands. Quite a range in quality and pricing. Could have purchased another tool that may have done the job for half the price of the Ridgid No. 345 Flaring tool but decided to bite the bullet and go for the best. Have done several flared tubings and it works fantastic! Very easy to use. The cone basically self-centers in the tubing and then you just tighten the flaring tool onto the tube block and after a few cranks of the lever out comes the perfect flare connection. A great tool for doing the job right. With Ridgid you get a quality product that will do the job...it's as simple as that! Buy this tool and you'll be happily flaring for years to come! Thanks Ridgid!! November 25, 2014
Rated 1 out of 5 by Doesn't hold 3/16" brake line Working on old brake line from a '04 Cavalier. Pipe measures .186". The first 5 or so test flares I did worked fine. Since then, the clamp won't hold the pipe - it just slips down when the press is applied. I am reluctant to make a blanket condemnation; all I can say for sure is, it doesn't work for me. YMMV.
