MFG. Part #:


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, its 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.

Item Details

Made in the U.S.A.


  1. We recommend using this tool only on soft material lines. Extensive use on 3/16" or larger steel lines may result in wearing out the tool quicker. We recommend using a lubricant on the swedge.
  2. If flaring stainless steel line or a great deal of mild steel line, we strongly recommend our ratcheting flaring tool 910-89524.
Some parts are not legal for use in California or other states with similar laws/regulations
