Overall Assessment

Customers highly praise the product's quality and practicality, particularly its adaptability across different materials like steel and aluminum. It's reported to create perfect 37' flares and proves invaluable in projects involving flaring gas and fuel lines. The tool's performance exceeds expectations, particularly in aircraft fuel system tubing and brake building projects. Easy and fast usage are highlighted. Some users recommend replacing wing nuts with regular ones for a firm grip and using lubrication for smooth operation. While working well overall, some notice that specific measures like ensuring flat sides and setting tubing height correctly optimize its use. It stands out as a good investment for hobbyists and home mechanics.

Nice tool at a good price

Used on 3/8" Ni-Copp tubing, worked fine. Use tubing cutter with sharp cutter wheel, remove inside burrs carefully and any outside ridge, make sure edge of cut is smooth and outside is chamfered slightly. Replace wing nuts with hex nuts for better grip. Use thin oil on screw threads and between point and screw. Practice on scrap to check stick-out for best flare (1/16" worked for this tube). Form the flare, remove tube and polish any grip marks. Inspect for splits and that flare doesn't overhang edge of collar. Ni-Copp forms nicely, steel is another matter.

works adequately if you know to fuss with it.

In order to get it to do the job, I replaced the wing nuts with regular nuts I could get a grip on. I greased the cone and cone threads. I took time to line up the sloppy clamp halves as I tightened down the holding bars. I could do the job on mild steel with no problem but forget stainless. It is a standard design and might be available cheaper.

I didn't want to spend a lot on a flaring tool but was a little concerned about the quality of a cheaper flaring tool. This one worked great and didn't cost a fortune.

For some reason AN flaring tools are no as easy to find compared to single/double flaring tools. I was glad to find this one at a decent price. The tool is definitely not a high end tool but it certainly does the job it's designed for. I do wish it was engraved with a little info such "AN Flaring Tool 45 deg" or something like that to make sure they dont get mixed up with the 37 degree stuff but it is what it is.

Easy to flare just like using hand flare for standard brake line flares. Same setup just different flare degree.

Don't waste your money on this. Litterally broke on the second flare. Wasn't asking much from it just a 5/16 steel fuel line. One of the clamping studs broke off in my hand making it impossible to tighten.
