Bubble flare

I thought the Double flare was not only stronger, but also re-usable compared to the Bubble flare. The 45 degree double is folded in on itself when first formed. The bubble will crush once fully tightened and can't be reused. Correct me if I'm wrong.

[@Ketovoregearhead]

Finally someone who knows what a bubble flare is. There are many videos titled as bubble flare but they're actually doing double or inverted flares. Thank you for not wasting my time.

[@OnlineAutoRepairVideos]

Mark, I AGREE WITH YOU 100%!!! Those guys are going to get someone killed! Just buy the right tool for the job, the set is not expensive!

[@danlevesque5437]

Or buying the brass adapter to convert the bubble flare to a double flare

[@robtrauth4518]

good video and thank you for clarifying the conversion because I have often wondered why its not the same as a double flare and this clears up the confusion

[@richarrrdj]

thanks for posting this. just bought lots of tools, fittings and rolls of brake line for doing my old gmc truck. This is the 3rd video I've watched this afternoon on youtube and yours is the best. Now I can get the bubble flare tool & get it right.

[@myastlabhelper]

Thanks for the feedback and glad I could help.

[@milomanx6531]

Unlike the other videos about bubble flare, this guy does it right. Milo Manx

[@HankScott]

Thanks for this good video. I've seen lots of other ones with people using double flare tools to make a bubble flare, which can be done but not as well as using the right tool. All of the car parts stores in my area carry the double flare tools, but none of them carry the bubble flare tools, even as a rental! So I ended up buying one on Amazon, and just wanted to see the proper method before I use it today. It seems like many people don't know the difference between double and bubble flares and that you have to use the right type that matches your vehicle or else it will leak!

[@phillipyounkins7432]

This is probably the best video out about this type of flare 😊

[@TheZeno4444]

His flare has the proper 90 degree, flat, contact point to fitting. Using a double flare tool to create a bubble flare creates a 45 degree slope at the fitting. Tightening to a slope creates a slippage point.

[@kym393]

Turn the clamp over, use the flat side and skip the next step of double flaring

[@RonGJX]

You are a born teacher. Excellent job.

[@myastlabhelper]

Thanks everyone. This is a Snap - On brand tool, however I've used many different types with pretty much the same results.

[@hippitymcstribbs4906]

The Mighty Mett says "Make ya more strong!" Lol

[@scuba6663]

There is a difference between DIn and SAE bubble flares and two different fittings that accept them. SAE is 45 degree and din is 90 degrees!

[@nbpt1000]

Good video but double flares are still used on cars today. The Double flare can be re-connected if removed and are typically still used on the connection to brake calipers and wheel cylinders. The Bubble flare, used elsewhere in the brake system should not be reused once disconnected.

[@mihir9330]

Great video on bubble flaring. There are very few videos on bubble flarings. thank u!!

[@grzegorz16100]

4.75mm is simply 3/16 of an inch. It is just the same diameter in different unit.

[@jimnugent4966]

3/16 inch X 25.4 mm per inch = 4.76 mm

[@MikeBrown-ii3pt]

Why have several different flare tool sets on the bench? I have 1 set that does double, as well as ISO (bubble) flares in sizes from 1/8"-1/2" tube. Mine is a Lisle set which cost less than $100. I can't use it on stainless tube, but I have another tool for that.

[@woodybear8298]

You should always flush the line with brake cleaner after filing the end to ensure there are no file shavings inside the brake line.

[@izzycamaro]

Great video on bubble flaring, thanks a lot. Have a great day.

[@robertwatson9599]

Good video for operation of tool. Not so good for actually doing lines. Your brake line will usually be a few feet long, and sometimes still installed on the vehicle. Avoid putting the brake line in a vertical position, especially in a class, bad habits start there first. Debris will fall in your line much easier as you work on it if it is vertical. Especially when filing or deburring. blow the line out or tip the open down and tap on it to remove debris. Practice holding the anvil tool while compressing the tubing, it is not too difficult to do.

[@fredkester6130]

good video

[@Mike-vk2ni]

Great video thanks my moms car needs to have new steel brake lines installed because they are all rusted out after watching your video I went out on ebay and bought me a blue point snapon flaring tool mine used yours is new but as long as it gets the job done that's all I care about thanks for the great video

[@daviddominguez7164]

It’s a good video I was having a lot of trouble making the brake lines of my vw bug. Now I know what I’m doing wrong.

[@SuperSultanTv]

I don’t think you explained how much material should be poking out of the vice

[@Rambone72]

Nice well explained video. What the brand name of your flaring tool used in this video ?

[@myastlabhelper]

That's a Blue Point from Snap On tools. All of the brands seem to work well though. Thanks for the feedback.

[@superinnovated]

Your far above all other videos Phenomenal demo

[@giftofnile]

Very Profesional flare. Thank you

[@tonyarthur2828]

Thanks

[@mikesstation7932]

Good Video What is the brand and model number for your flaring tool. I also bought a cal - van bubble tool like the other man, and I could not get it to make a bubble flare (its a piece of junk) Thanks

[@craigbartley4848]

Specifically, which tool are you using? Brand, etc. Thanks.

[@geoh7777]

I didn't understand what you said toward the end about moving over to the bubble flare. If one's vehicle is older than 1995, wouldn't all of the master cylinder and brake cylinder ports be machined to acept the double or single flare?

[@kris8263]

Yes they are machined to accept a double flare, so changing them out just for the sake of a new standard is costly and pointless. Maybe what he meant was using a bubble flare union instead of a double flare in case you need to splice the line that rotted out.

[@kylandaminick13]

Thank you so much for making this video. I didn't know that you just use the 4.75 mm sized tool for a 3/16 line. It was driving me crazy trying to find a bubble flaring tool for a 3/16 line, so thanks again for saving my sanity.

[@myastlabhelper]

Glad I helped. Thanks for the feedback

[@michaelmounts1269]

so...can you make “saginaw” gm style double bubbles this way w. o-ring?

[@dirt41gto]

Where did you get the flaring tool from?

[@bestbuildpc]

Thank u sir. Today I was having a problem with bubble flare. I made a bubble flare with a double flare fitting and then it started leaking. Now after watching ur video I realize I must make a British bubble flare in order to fit double flare fitting stainless steel so it can seal nice and smooth. Gonna try tomorrow. Thanks!

[@ocsrc]

Can anyone confirm that a 1991 Ford Explorer 2WD with ABS has a bubble flare on the lines going to the master cylinder ?

[@dougontheotherchannel3078]

Yes, I can confirm

[@Passionate747]

Excellent presentation best video .

[@kyhomegarage3430]

Very nice presentation thank you for time and effort to make this video cheers.

[@romulan1129]

I am trying to no avail to make bubble flares. I can easily replicate over and over double flares, but still no bubble flares. I am using the Cal Van tool which is supposed to be superior. I think the reason for failure is because the die for bubble flares is much longer than the die for double flares. It has more metal to push and I am working off a roll of brake line, so my brake line is not completely straight. I just wonder if the KD or blue point bubble flaring tool would do it.??? Its die seems a bit different than the Cal-Van die...... Any ideas?

[@RktsledTv]

Thanks for this video helps a lot

[@williamhaines856]

great ur a great teacher

[@rayirvin832]

Where is link for tools?

[@tomfloyd8282]

I didn't see him put any oil on before he flared the line so you do or dont need oil.

[@lazyman2473]

not oil but a drop of brake fluid

[@brockxxxxsamson]

3/16" = 4.76mm

[@UnderTheRadar1976]

My tool seems to make them to flat

[@blackiechong4344]

gSome of these videos say tighten as much as you can and this video says finger tight. Who is right?

[@myastlabhelper]

So the answer is in the tool. really. I've had some of these flaring tools, usually low budget ones that have no grip on the line whatsoever so, here I'll tighten with a bit of extra elbow grease, usually a screwdriver between the wing nuts. Hope this helps.
