Notes

The main issue when dealing with aluminum tubing (or any aluminum for that matter) is that it “work hardens” when it flexes, which can lead to cracks. It is important that the hard line is isolated from vibration and movement.

Clamp the tubing securely with rubber coated clamps (Adel clamps) and use bulkhead fittings where the tubing attaches to the flex line. Never run the tubing directly to the engine without a flexible hose section. If installed properly, aluminum tubing is safe and durable.

Deluxe Flaring Tool, 37 Degree AN
                        

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.
