Notes

  1. Brake System Builder's Tip (Link) 
  2. The manufacturer recommends using this tool only on soft material lines. However, we have had good luck using it on 3/16" steel lines. Extensive use on 3/16" lines or on larger steel lines may result in wearing out the tool quicker. We recommend using a lubricant on the swedge. Deluxe tool 910-89528 is recommended when working with steel tubing exclusively.
  3. If flaring stainless steel line, we strongly recommend our ratcheting flaring tool 910-89524.

only good for soft copper

September 17, 2012
I ordered from an older catalog that did not have the "not for use on stainless" note. I attempted to flare a stainless brake line and ruined the cone on the first flare. The new catalog covers that problem
No, I would not recommend this product.

simple and easy, makes the job smoother

June 29, 2012
easy to use. good construction. accurate flares. plastic caps on ends of handles are poor idea as they fall off when using, epoxy on the caps or press ends so they can't fall out will cure this situation. priced right for quality of tool
Pros:
  • Easy To Use
  • Accurate flares
Yes, I recommend this product.

Worked just fine

June 24, 2012
Simple to use. Only annoyance was that small rubber end caps on tee handle fall off easily, but this does not affect functionality. Used to create AN type fuel line set up for my three deuce setup on my 68 Vette. Very happy with results.
Pros:
  • QUALITY PRODUCT
  • Easy To Use
  • Consistent results
Yes, I recommend this product.

China garbage. Broke during 3rd flare.

April 18, 2012
I bought this to flare some mild steel 3/16 line and it couldn't do the job. On the 3rd flare, the inner edge of the tubing dug into to chrome-plated pot metal flaring cone and created a huge groove making the tool unusable. Also, as said in another review, the dies do not meet properly (gap on one side) causing uneven flaring.
No, I would not recommend this product.

Works as advertised.

January 02, 2012
This is my first attempt at 37 deg. flares but from previous experience with reverse 45s put a few drops of lubricant (I use 3 in one) on the die before attempting the flare. This eliminates uneven and torn flares. Also practice a bunch on some copper tubing. It helps once the tubing is clamped to put the whole thing in a vise so you are not looking like you need three hands while flaring. After several practice runs move up to the tubing you intend to use and again, practice until you are satisfied. Although the tool is pretty much self explanatory to anyone with experience it came with no instructions which prevented me from giving it 5 stars instead of the 4 I gave.
Pros:
  • Lightweight
Yes, I recommend this product.

Good price, poor die quality

July 08, 2011
Used it on 5/16" tubing when I first got it and it worked fine. Die halves didn't mate up perfect but good enough. Few months later I used it on 1/4" aluminum tubing and found that the 1/4" die halves when closed aren't round but oval so it won't close around the tubing without crushing it and the die halves are 1/16" apart when clamped on the tube. Also, the top of the two die halves aren't at the same height or shape so the flare is very uneven. I may have just gotten a bad one, most of the dies look ok but the 1/4" is unusable and the 3/16" looks worse so I'd have to say poor QC. I'll have to buy a different, better one now to finish my job.
No, I would not recommend this product.

Does this flaring tool make a double flare?

January 11, 2011

Does this flaring tool make a double flare?

Answers

No, this tool will not make a double flare. This tool, part number: 91089529, is for use on 37 degree "AN" type fittings. Many OE brake parts are built to use 45 degree "double" flares. In some applications, using the 37 degree single flare on a 45 degree double flare will cause a leak. However we do sell the tool that you will need. We suggest, part number: 91089525, 45 Degree Double Flaring Tool. This is a handy tool to double flare mild steel brake lines just like the brake shop does. This tool makes 45° flares only. For 3/16", 1/4", 5/16", 3/8", 1/2" mild steel line only, this tool is not to be used with stainless steel line.

Deluxe Flaring Tool, 37 Degree AN
(Part #91089528)
                        

This is the tool you need to make the 37° flares required for AN fittings. Standard brake and fuel lines are flared at 45° which are not compatible with AN hardware. This tool forms stronger flares assured by a smooth, even radius formed at base of every flare with its precision machined chamfer. Plus, it's also self gauging - just insert tube flush with top of die for accurate flare size.

  • Hardened steel, chrome-finished cone makes exceptionally smooth, high-strength flares with a radius at base of
    flare – instead of the sharp angle formed by ordinary tools
  • Slip-on yoke permits use in tight quarters
  • Allows flaring where there is little space between nut and tube end
  • Feed screw design provides smooth, easier operation
  • Positive gripping and self-gauging of tube for exact flare size
  • Sliding die blocks lock in place by clamp action

Works on 3/16", 1/4", 5/16", 3/8", 1/2" and 5/8" OD tubing such as aluminum, copper, brass and mild steel.

37 Degree Flaring Tool for Stainless Steel Line
(Part #91089524)
                        

This is the best flaring tool for the money we have found. It has a feed screw with a hardened flaring cone eccentrically mounted in needle bearings which produces a rolling action for even metal flow. This provides uniform wall thickness without galling. It will put a 37 degree flare in 3/16”, 1/4”, 5/16”, 3/8”, ½”, 5/8” and 3/4” tubing. We recommend this tool when flaring 3/16” stainless steel brake line.

  • Provides smooth, uniform flares with minimum effort
  • Feed screw handle requires less motion and effort than standard handle
  • Flares steel, stainless steel, hard copper and brass thru wall thickness of .035"
