View Full Version : Any Reason To Make 37 Degree Flares?
I just bought the Eastwood turret flaring tool that came with 45 degree die set. Is there any reason to get the 37 degree set, too?

If you're running AN fittings, the 37 deg is needed
If you're running AN (or JIC) hard line you may have a need for the 37-deg flare but if running AN hose the fittings already have the flare.

45* has less of a variety of fittings. Good for brake lines as thats how they are premade. Tons of pieces for brake systems available locally.
37* AN has a world of selections, easier to custom build a fuel system.
I have both turrets, built my brake system in 45, fuel system in 37. Do some research, see if what you want to build is available in the 45. If not, you may have to get the 37.

Exactly my experience as well. When it came time to pass my front brake lines through the front of the footbox, I wanted to use bulkhead fittings rather than holes with rubber grommets. Could not find any 45-deg fittings that would allow me to do this, but there were tons of AN options (37-deg). So I sprung for the set of 37-deg dies. Also ended up using them on my fuel lines, but overall they got far less use than the 45's. Most folks can probably get by without the 37's, but like any other specialty tool, when you need it you need it.

Exactly. I used the 37* die to flare my fuel lines, and then Earl's tube sleeves, tube nuts, and reducers to transition from the hard line to the braided steel soft line.

I just received my Hydroboost from Forte. Banjo fittings with AN ends are used on the master cylinder. To connect my hardlines to the banjos I needed 37 degree flare. Luckily, aviation uses strictly 37 degrees and my local A&P made the flares for me. Now I know 45 degree, inverted flares are preferred, but due to the setup I had, didn't have much of a choice without introducing numerous adapters.

In a pinch you, can get by with a 45° flare mating to AN if you are working with aluminum hard line. The aluminum is soft enough that the nut and sleeve will re-form the line to conform to the male 37° AN fitting. Obviously, having the correct flaring set is best, but as I said, in a pinch, it will work fine with no trouble.
