Mastercool flare tool

[317millhand]

Im thinking of getting the Mastercool universal hydraulic flare tool set number 71475. Will the Mastercool tool double flare hard stainless lines? I have a stainless line kit from Right stuff and need to add a prop valve in the front to rear line and convert to flex lines for my new rear discs. This is not the annealed type tubing. Eastwood sells what looks like the Mastercool set for over $500 and says that it will not do stainless. I want to get a good tool that I can keep forever and use on other projects in the future. By the way Eastwood has a nice tool out now as well that is my other choice. http://www.eastwood.com/professional...ring-tool.html

I have had a Snap-on flare tool for 10 years and it works great.

i haven't done SS with it, but a bunch of guys here have. you shouldn't have any problems.

[oestek]

We've got that Eastwood pro tool and it's really nice. We've not double flared stainless with it yet, but I'm confident it would have no problem with it.

Will it double flare stainless. I've got a good rigid brand flare tool that will single flare even the hardest stainless, but not capable of double flaring. Some folks say the hard stainless lines do not need double flaring, but I get alot of different views on this.

And I also saw some yes and no discussions if it will do SS. The eastwood tool says NOT for SS. And it is the same tool as the mastercool. I think they are all the mastercool type, havent seen any that are not.

I have the MC but havent done any SS. The only issue I see would be the clamping die being able to hold onto the tube with enough force to keep it from sliding. The pump will bend it, but it may try to push the tube out causing a short flare.

And for me thats the major downfall of most flaring tools, they just cant grip the tube with enough pressure to keep it from creeping when the flare is being formed. JR

Ok Ill add a lil more opinion. Double flare or single. The double flare is used IMO on soft steel tubing because the cut edge is so soft and thins out with a single flare and the double flare basically creates a new edge by folding the cut edge in. So you have a thicker outer edge on the double flare and its not gonna tear or thin out. The thinning of the metal on a single flare is what causes them to fail.

Now with stainless it may not thin out as much as the soft steel brake lines. And I say steel but they are not steel, not completely. I thought I remember reading they do have copper or some other soft metal in them. Maybe not. But, if the wall thickness of a stainless line was sufficient to be able to thin out a lil without becoming too thin then a single flare should work. If it is gonna be a single flare the cut needs to be perfectly square and burr free. Now if the wall thickness is too large I dont see you double flaring it. Any idea what the specs of the stainless brake line is? And it is brake lines right, cant use stainless tube not meant for it. JR

Why do you need to double flare stainless?

[BonzoHansen]

I thought the need for double flare was because of the seam that SS does not have.

[MonzaRacer]

Why do you need to double flare stainless?

Yes all automotive brakes systems with inverted flare needs double flair or it will leak.

UH NO, double flare uses the crimping action of the inverted part to get a high pressure seal, single flare is only rated to like 200 psi or some such low number. Remember it from IVM class in tech school.

As for the Mastercool hydralic flaring tool, BUY ONE!!!!!!!!!!!!!!!!
You will NEVER GO BACK unless you have too.
It will also if its big kit, give you the ability to do ISO or "Bubble" flare, GM old school FI fuel filter flare thate uses the orings and FI style filter. And it will give you the ability to make the push connect flar for say Ford fuel filters too and lots of stuff like buying the 37 degree adapters give you a way to to the AN flare too.
I spend $468 on snap on truck and its best nearly $500 investment I have made yet.
I even use the older GM fuel line flare to put a rib on fuel lines and tranny cooler lines when using hose clamps, the hose will never slide off unless it gets a LOT of pressure.

[MonzaRacer]

Oh yeah saw one on Amazon.com for like $300 or so. AFTER buying mine but I financed mine when up grading my DSO too.

Then I have been misinformed, thanks.

I got it today and tried it with some scrap tubing. Made a good straight cut on the tubing with a bandsaw and filed of the rough edges and reamed the inside. It double flared the 3/16 stainless tubing perfect on the first try very quickly and then some 1/4 inch stainless brakeline perfect as well. The dies clamp down very hard. Good quality that is definately worth the price. I believe it will handle whatever you throw at it. I paid $275 for the universal kit that will handle all the things monza racer mentioned. They also have the kit that does only the double flare and push connect flare for $235. heres where i got it after searching for the best price http://www.tooldiscounter.com/ItemDi...ookup=MAS71475

The toolwarehouse has a guarantee 110% price matching policy. NOT!!!! They want 331 for the 71475 kit. Tool discounter sells it for 275. Would they match it??? NOPE. So with the 12 bucks of shipping the Tool Discounter still kills them.

Whats up with a written guarantee?? Guess it only holds true if it suits them. They should prolly re-word their guarantee to suit their needs.

Just shows, I does pay to shop around.

275 for that set is a STEAL!!! Get one there if you were thinking about it. Thanks Millhand for the link for the great price!!! JR

why wouldn't they match it?

ive been intending on using a single 37* flare for both the brake and fuel system on my car. i had initally heard that this wasnt a problem as long as the proper tube nuts were used and the fittings were converted pack to pipe thread at all the inlet/outlets. after reading the above, i decided to do a little more reading.

the consensus was that double flaring was three fold. first, it provided a stronger flare in weaker tubing (aluminum), it allowed it to crush and therefore seal, and it folded the outside seam over, thus putting it on the inside and out of the way of the seal. seamed tubing that is single flared WILL leak. some success has been had with using the soft metal washers in the joints to act as the double flare does.

also, i looked into the pressure ratings, and although this is only one site, it says that 3/16" stainless tubing with tube nuts is rated to 5000lbs. they state a 4:1 safety factor, so im not sure if that puts it at 20,000 psi, or the more likely 1,250 psi.

heres the link http://www.sealexcel.com/37degree-fl...ressure-rating

hopefully somebody will have access to accurate numbers from a published manual.

my plan was to buy the 71480 which only includes 37* mandrels.

The sales guys I spoke with, Lee was his name said they would take a loss. They would loose money. Guess they dont have as low of a pricing from the manufacture as the other dealer. Just how things work, different pricing for different dealers. And I get that, but dont say you guarantee your pricing. Theres no guarantee there. They lost sight of what a guarantee means. Pretty sad if you ask me. They want to puff themselves up touting superior pricing and they are sure of it, no matter what so they can toss around guarantees like they were words in the wind. Weak is what I see. They cant hold true to their word. Thats poor business. Almost sounds like a politician. Yeah, I guarantee Ill do this and that if you elect me. The crunch comes and they talk out of the side of their mouth. Mumbling all the while trying to say why they couldnt hold to their word. Decent business owners held true to their promises years ago. Even if it meant taking a loss. Not so anymore. JR

Oh yeah. Ill add, its not about the money, it was 20 bucks after all was said and done. But its principle. I piss away 20 bucks at a moment. But the principle of staying true to your word is what gets me.
