How to make a HHO Flame/Flashback Arrestor

[MaN1aC666]

how long do they last ?

[bartley440]

@MaN1aC666 Good question... Not sure, I haven't had the time lately to work on my HHO experiments :0(

[MaN1aC666]

@bartley440 alright i'll put it to the test lol ... :P

[Video85Man]

thanx 4 the vid man

[richardlyew]

a million thanks sir!

[Majorupheaval]

My kind'a design. Cudos.

[merdekamotor]

please tell more detail how to make it again

[Iseekoutthetruth]

I thought those bubblers where one way, do you still use this flashback arrestor setup?

[bartley440]

@Iseekoutthetruth Yes

[keerthivash]

it is agreat idea and i tried this at my home it worked greater than bronze wool. thank you

[magicmachine1]

5 Stars!!!

[viper19861986]

seems simple enough and enough people claim it does not slow down the flow rate.

But my question is WHY? A bubbler seems to work just fine. Always fun to light the tube and have it hit the bubbler and BOOM!

[bartley440]

Bubblers are good for automobile applications as scrubbers, it helps to keep the KOH out of the engine. Most people use a flashback on their torches. What ever works for you.

[viper19861986]

@bartley440

i thought KOH and KaOH do not ever go up with HHO, they are a true eletryolyte(sp)

KOH and KaOH will stay in the bottom of a bucket, even if you leave it out in the sun all year?

So it would never hit your car :)

not trying to diss your video but tell me if i am wrong, i like to learn new things.

*5stars*

[myztic123]

@viper19861986 i just had a bubbler completely explode, i'll use a flashback arrestor next time

[myztic123]

@viper19861986 Two of my bubblers exploded already, i'm going with an additional flashback arrestor now.

[schematica2]

I don't have time to make a video right now, but your video inspired me to really take a good look at this arrestor. I made a few changes. I found by twisting I could totally remove the plastic core, which I later filled with bronze wool. Also, I check the flow, and ground the stones down to accommodate the direction of flow, added some o-rings, and filled all empty space with bronze wool. Have not had a failure yet.

[bartley440]

Its great when someone can take a good ideal and make it better. Thanks

[schematica2]

Exactly! I would never have thought of the stone myself and was amazed how cheap but effective an alternative it has provided over more expensive methods.

[danielhattie2000]

how much does this restrict the gas flow?

[bartley440]

Good question. I haven't measured the exact flow before or after so I can't really say. But with that said I don't think its that much to worry about.

[danielhattie2000]

i went and bought some airstones and they dont restrict much but i was just blowing through them.

[schematica2]

I have not noticed any restriction in gas flow.

[schematica2]

Before and after my own modifications to bartley440's design I found no appreciable restrictions on gas flow.

[schematica2]

Bronze wool is highly over rated as a component of flash back arrestors. I would never rely on it by and of itself as a method of dealing with this potentially deadly problem.

[schematica2]

What amazed me is the fact that the dimensions according to your parts list and my own investigation and purchases it that there is a rather large gap between the stones and the fitting. I figure the glue closes this gap, at least enough to make it functional. But, without a solid mass around the stone to remove any space I am sure the gas will eventually creep into the arrestor. It might be better to force epoxy around the stone in a thin slurry and let it dry to gain a safer arrestor.

[bartley440]

Correct, You want the HHO to go thru the stones not around them. That's why I glued them to each end. You could also put a rubber spacer between them to keep them pushed against each end of the fittings.

[schematica2]

PS: I paid $1.49 for a two pak at Walmart.

[bartley440]

PetSmart too!

[schematica2]

The only " stone bubbler's" I found were marketed by Aqua Culture and semi-rounded on one end. This is opposite the plastic hose connection which you remove in your video. I can only assume that these rounded ends go into the brass fitting, which is rounded to about the same dimensions. Is this correct?

[pietzeekoe]

do you need to keep the stones moist?

[bartley440]

No, never had too. Worked fine dry.

[dzgfdg]

so that means u never have to wet it and check on it periodically?just leave it as it is?

[bartley440]

I would recommend checking it periodically just because it's a safety device. Never assume! Safety is no accident.

[scuffieduffie]

so with other words.

if you dont have this you blow the shit up ?

[bartley440]

if you notice atthe end of the video the flame travel stops at the flashback arrestor. If you don't know already HHO is very explosive!!!

[schematica2]

Without an arrestor, yes you do run the chance of blowing all your hard work up, not to mention possibly being hit by shrapnel and caustic solutions that will melt your face off.

[moonielo]

about this video, you have got to show everything more closer because from this kind of view, i am totally lost in what to do, like after drilling the plastic out from the stone bubblier, how does it really go on to the wha-chu-ma call them things?? but overall, awesome flashback!

[menzup123]

Hi!

I dont get it, how does it work? What is insidet the brass coupler?

Nice work dude!

[bartley440]

It's called a bubbler stone. People use then in fish aquariums. You can get them at a pet supply store. Not sure where to get them in Poland?

[menzup123]

Oh thanks, i didnt understood "Stone Bubbler" in your movie, now it's clear for me. Is it 100% reliable ?

Bubbler stones are available in pet stores in Poland too ;)

Thanx for answer

[Kingflight1]

This didnt work for me my cap blew off my bubbler luckily i didnt glue it on.

[bartley440]

Sorry to hear about that! Mine is working just fine. Maybe you didn't build it correctly. Watch the video at the end. HHO is dangerous, always protect yourself. Your channel profile says you're 13.

[Wayneman1234]

Bartley. your video is great. I will try it soon.

have you ever thought of using the old 4 barrel rochester carb filters. they are small, like the blue arrestors, but mad of brass, or ceramic. should work good. i will try.

[thegreatkoua]

nice where do you buy the stuff

[bartley440]

Home Depot or Lowes

[SthealthRaider]

does this actualy works?

[bartley440]

Did you watch the end of the video? You can see how the flame travel stops at the flashback device. It works fine for me.

[IsItTrue99]

Nice one dude. Really like it, nice test too. Thanks for the video gunna use your design

[pgpeachess]

the stone bubbler will disintegrate after a while(mine did). i use an in line gasoline filter filled with bronze wool. neat work!

[sumbich]

yeah, just today, mine did too. I noticed blue coloring in my hosing and after checking, deduced that it melted. :( I guess fine bronze wool wins... :)

[bartley440]

Believe me bronze wool will burn too if the HHO gas stays lit inside! I think a check valve would be the way to go, like the ones they us on welding torches.

[maituub]

Indeed those blue cheap aquarium aeretor stones,

can't stand up against a caustic mist ( from your electrolyte), they pretty soon will fail.

The same design, but with sintered metal brass or better SS from an compressed air silencer would be better;

and screwed not glued.

[hydrobenman]

Hey, I copied your flashback arrestor and am very pleased with the results...check it out...Thanks for your help..

P.S. tried to give you credit at the end but it got cut off some how....

[bartley440]

No problem, glad I could help. That's what this HHO community is all about, sharing our ideals so we all can benefit in the long run.

[AudiMoney]

oxygen or setaline flashback arrestors is what i have been testing for months and i have had no problum... ill get you a part number tonight.

[AudiMoney]

you dont have to make your own.... you can buy one from Lowes, Home Depot, and welding supply stores.

[bartley440]

I couldn't find any at either Home Depot or Lowes in my area. Do you have a part# for a online search?

[bartley440]

Also I heard that that Hydrogen is too small of an atom and burns too quick for the oxygen or setaline flashback arrestors to work.

[hydrobenman]

This looks like a very good flash back arrestor I belive its the best one I have seen great job...how did u know this would work?

[bartley440]

At the end of the video you can see that the flame travel stopped at the Flashback arrestor. Thats why I turned the lights off and slowed down the video to get a better picture. I've ignited the HHO multiple times without a failure. I would recommend a bubbbler with the Flashback arrestor because you can never be to safe working with HHO. I hope this answers your question.

[schematica2]

The tremendous temperature generated by hydroxy gas demands a very large amount of oxygen to continue the reaction. The small capillary tunnels of the stone cause the oxygen to be expended quickly.

[wesh234]

I really like this flashback arrester, but where in line does this piece go? is it near the intake or just anywhere? thanks

[bartley440]

Good question! I would recommend putting it near the intake to minimize the amount of potential gas build up between the intake and HHO generator. Hopefully this would reduce the amount of damage if the engine backfired.

[schematica2]

I think the best place is closest to the source of any open flame, which is going to be the intake. So IMO it should be about 6" to 12" from placement on the intake placement.

[steven78203]

Dude, you are the man with the master plan.Two thum's to ya bro!

[ZiggyScrubs]

Sorry....... I now remember seeing that last night, when I first watched the video. When watching today, I didn't watch it to its ending... My Bad!

Thanks!

[ZiggyScrubs]

Great Job, very good instructional video, I was wondering what people were talking about, "stone bubbler arrestors"!

One thing though, just for the convenience of viewers like me, could you please comment on the exact size pipe/fittings you used (maybe even add it to the "more info" area of this video).

Thanks for putting this vid up!

[bartley440]

I do have a parts list at the very end of the video. It's just your standard brass 1/2" by 2" coupler with brass 1/2" ends with 3/8" barbed fittings and Teflon tape.

[sumbich]

Awesome vid. Thank you for the info on howto for a simple arrestor. :)
