Mastercool 72475-PRC Universal Hydraulic Flaring Tool Set – Patented Design – 45° Double & Single Flares, Push Connect, GM Fuel Line, Brake Line – Includes Hydraulic Ram & Mini Tube Cutter

Pricey but so good! I've done several brake lines and trans line with this unit and no leaks

Item delivered,as advertised. The box was torn open, delivery driver placed the item against the gate leading in to my yard. The packages are supposed to be placed on the front entrance step. Very unprofessional.

Great tool for doing brake lines!

Very good quality tool. Easy to use

This master cool hydraulic flaring kit is phenomenal! It has so much versatility, makes flares, double flares, push to connect lines and making bubble flares a breeze. Early on when I got the kit, I was very frustrated with the fact that the T-handle does not apply enough clamping force on the dies to prevent the line from sliding out while initiating the hydraulic press portion of the tool. It was highly frustrating to the point where I was about to return the kit. However, I realized that the T-handle is removable (there’s a threaded knurled nut on it) so I removed it and opted to use a 13 mm shallow socket with a flex head ratchet to make sure I get that extra bit of torque to really clamp down the die. That’s the real trick with getting this kit to work. You just have to make sure the clamping dies are really tight, I just couldn’t get them tight enough with the T-handle so I used a 3/8 ratchet with 13mm to snug it just a bit more than you could with the provided T-handle, once I did that the tool worked perfectly! I’m a DIY guy. I’m not even a technician but if I were a technician, I would absolutely buy this kit. It is worth every penny and will pay for itself with one job. Just think about what it would cost you to pay a mechanic to do this type of job on your vehicle. You’re saving a ton of $$$.

Seems like a nice quality product, But it does not come with directions or instructions on how to use. So if you've never used a similar tool before you may struggle to figure out the operation.

Nice tool set. Works well.

Dont make the mistake I made and screw around wasting time with the cheap flaring tools that screw down by hand or you crank with a lever... I literally sprained my elbows or strained them and theyve been hurting for a week now. I ordered this tool as I have used one in the past at our old shop and it double flared stainless 3/16" line with ease. I found Mastercool to be a good brand name supplier of this type of tool, it works the same. I was able to leave my stainless line on my truck with the leaking fitting pushed back, I straightened the line by hand. After cutting the end off, I followed the instructions as provided to double flare 45 degrees. In the wheel well, the tool fit and flared my line easily. I tightened the fitting back down at the tee and it sealed up FIRST TIME. Also the flare was perfect looking! WOW! I messed around before and found out.... save yourself time and cuss words!!!
