Mastercool flaring tool?

[SteveU]

Toolwarehouse.net shows a mastercool universal flaring kit for 331.95 but has a 37* flaring & double flaring adapter set right below it for 70.25. My question is, are these already included in the universal kit & if not, what are the 37* used for as opposed to the ones that are? Really don't want to buy something extra just to find out it is already included in what I'm planning on ordering.

what are the 37* used for as opposed to the ones that are?

The 37 degree flaring tools are for aircraft if I remember correctly. :dunno:

37° are used for stainless steel brake lines in street rods... uses an AN type fitting

Be careful when you talk about AN fittings. You have the AN then there are the Industrial fittings (JIG) they look the same but I believe the AN has a different root radius then the industrial.

So for someone doing regular vehicles brake/fuel lines everything needed is in the universal kit? Want the ability to do both foreign & domestic cars as we work on both.

i have never seen a 37deg on a vehicle. maybe a link to the set your looking at? for complete coverage you'll also need a bubble flare tool.

You guys are muddying the waters a bit...

37 degree single flare is used on hydraulic fittings, better known in industry as JIC. They are typically sized using SAE sizing (fractions of an inch) but sometimes, they are sized using AN sizing (sixteenth of an inch).

AN is interchangeable with JIC, except they are commonly measured in sixteenths. Aftermarket automotive manufacturers have latched on to the AN system because it sounds sexier and they're able to get more $$$ for their stuff. AN was originally developed by the armed forces... stands for Army Navy...

To answer the OP's original questions--you will never use 37 degree flare unless you have aftermarket hydraulics or other plumbing on your car. Even if you do, you may never use 37 degree flare unless you are redoing all of the brake pipes and decide to switch to "AN" from whatever comes on your car (usually metric bubble flare for asian and european cars, or 45 degree double flare on american cars).

Having said that, there's nothing wrong with "AN" brake lines. A lot of stuff in the automotive aftermarket is available using this standard. If you want to replace all the brake piping on your car you'll just need some adapters at the calipers and MC, and everything else can be "AN"... then you can put your 37 degree dies to use :)

Skip the add-on set. What you're looking at is an awesome set by the way. Those hydraulic crimpers are sweet, just a bit expensive... but if you're going to be doing a lot of brake and fuel line work, it will pay for itself in no time.

Edit--its interesting that the addon set comes with 37deg double flare dies. Can't say that I have ever seen a 37deg double flare on anything. WTF would that be used for?

[petty4243]

I would say the 37 degree set is an add on to the master set.... like already mentioned, would likley collect dust unless you have a specific use for them

[alex71]

agreed ^^^... I'm just wondering what 37deg DOUBLE flare would be used for. Single would be used for AN brake pipes and hydraulic lines...but what about 37deg DOUBLE? is anyone aware of an application for that? just curious.

[krusty the clown]

i agree. the only place i see 37deg flares is on harley-davidson oil lines.

Wasn't it etooldirect.com, that was listed here a bit back as the cheapest place to get this tool. I read thetoolwarehouse has a price matching policy, so you might want to check and use that.:thumbup:

[petty4243]

not sure about cheapest, but have seen them on ebay cheaper than op listed
