Capri Tools 3/16 in. Double Flaring Tool (CP21110-316)

Awesome. Perfect tool. Literally saved me on a late Sunday with messed up brake lines. It worked so much easier and bette than those junk ones. Flared the line in like 5 mins. The basic version (the non dual head) does both bubble and double flares also btw, had a bit if confusion with that.

Easy, quick, and effective. I had to double flare a rear brake line that was still attatched to my truck and in a tight space that the old wing nut style wouldn't fit into so I gave this one a shot. Laying on my back under my truck, in the driveway, in a tight spot up against the frame with about 3.5 inches of line to work with, this tool did a perfect, easy, double flare. Well worth the money spent. Highly recommend.

Incredibly easy to use. Having never flared brake lines before I was curious as to how long it would take me to make effective flared ends. First one out was perfect as were the rest of them. For prep I filed the end to make sure it was flat, filed a small bevel around the end then lightly de-burred with a utility knife. Followed the instructions for the tool and the results were great.First flare was on a scrap piece of typical steel 3/16 tubing which required just a bit more torque to seat the die using a 17mm ratchet wrench. The rest of the job was using 3/16 NiCop tubing and it super easy.

Have formed over 6 lines with double flared ends and have had no problems. Just cinch down line after getting it aligned with their tools and follow their instructions. This works great. just remember to add the lube so ends have easy time forming. Also dont be a Gorilla, just cinch tight. You know when its firm and you don't have to scrunch it more. I have used in vice without handle and with handle alone and both formed the fittings well.

Great tool. Flaring brake like is a PITA, and also very critical.Used a generic tool for decades. Had a couple leaks on a recent project and decided to give this a try. Did some practice runs and they were all perfect. Redid 2 lines and 7 flares on the project and they all came out perfect.Great tool for a critical job.

I'm nearly 72 1/2 Years of Age, & just have bent My own brake lines for the 1st time 😉. My take on this tool is it is a good idea, & never having flared a brake line in My Life used it & had a useable flare on the 4th go round, so it is easy & effective. My concern with the tool is it is made of some type of metal alloy instead of steel. The way You have to set this up & then insert the OP Bolt that actually creates the flaring puts a tremendous stress on the other parts of the tool & quite frankly I was leery that it may strip out due to the alloy metal it's made of. There are a couple of other concerns with it also-the machined out "tray" that the brake line sits in needs to be knurled in some way to keep the OP Bolt from pushing the brake line out & w/o the knurling You really have to crank down on the 2 locking bolts to keep it from doing so which brings up a couple more concerns, - the locking bolts are not all that substantial (& again You're screwing them into metal alloy) & if You look at how the tool is designed the 2 locking bolts are at an off set to each other leaving 1 corner of the tool w/o a bolt holding it together at that point (AGAIN You really have to torque the 2 main halves of the tool together to keep the main OP Bolt fm pushing out the brake line) it would make more sense to Me if there were actually 3 or 4 locking bolts instead of just 2 to hold the main body of the tool together. Yes, it does work, & it didn't brake/strip out, but if it would have been made out of case hardened steel instead of metal alloy & also had (preferably 4 instead of 2 locking bolts) & the 4 locking bolts being made out of a heaftier size case hardened steel I would have given it a 5 Star rating. 1 other thing, I actually had to take the handle off the tool (it just screws out/in) & put the main body of the tool in a Vise in order to flare the tubing. I can't imagine having to crank down on the OP Bolt how in the World You could flare the brake lines with them installed on the Vehicle w/o having to use a Vise. If You can, mo' power to You, You're a "better Man" than Me-😁 ! THE LORD Love's You !!! Best, PawPaw C

I used this to replace a damaged brake line fitting from when the prior owner stripped the threads on a master cylinder and the brake like is stainless steel. It worked as it should, and I was able to properly flare the brake line.

I don’t normally leave reviews but I had to on this one! Best tool I’ve ever used on flaring brake lines. Small enough to get in tight spaces while flaring on a vehicle. Super quick and easy! Don’t waste your money on the old style, you’ll be way ahead of the game with this unit! A little pricey in that you need a separate tool for each size but I’ll definitely be ordering others for my tool box!
