Fluval in a KR808 Cartomizer

[JimStanmore]

I read in a thread (can't find it now) about removing the filler from a cartomizer. Using that I disassembled a cartomizer that had seemed dead. Sure enough, there was the burn in the paper and the filler material. I was curious, so I tested it on a battery and it still heated.

On a whim, I cut some Fluval into 1/8" by 3/8" by 3/4" strips and slipped them (3) vertically (skinny end in) into the cartomizer spaced around the walls to replace the filler I removed. The paper had also been removed with the filler material. You have to be careful when slipping it between the tube or wire and the wall, I am using small tweezers (one side in the carto.) I pushed the Fluval down to the level of the tube.

First fill was 30 drops of a thicker juice that normally doesn't work well in a carto. 8 or 10 large cloud vapes and then a flavor change. The carto was almost dry. Refilled with a pg juice and it has been going about half-an-hour.

Next, I am going to leave the paper in and try a little thicker Fluval. I am not sure about the taste - sometimes it is better and sometimes it is the same or worse than the original carto. At least I may be able to save some of my dead cartos.

I just tried anothother one and left the paper in. The flavor is a lot better .

Is this the video that you got the idea from?

YouTube - E-Cig cartridge Fluval re-stuffing 101

Thanks for sharing that video. Unfortunately, that is not where I got the idea for removing the KR808 filler material, that post was about removing the filling from a cartomizer. It is post #21, fletchfx, in http://www.e-cigarette-forum.com/forum/kr808d-1/55722-refills-when-do-you-toss-carto.html.

I learned about Fluval from the mod site and trying the polyfil, PTB, and blue foam with 510's, 901's and 801's (like the video.) I am actually using Fluval filter insert, which is fish tank filter material that is more rigid than in the video. Info on this is in the cart mod section.

I did not want to try the polyfil type material because it seemed too flimsy to pack evenly. I was also just curious about the more rigid material.

Keep us updated, I think if you could successfully restuff a cartomizer, it would save us all a lot of money

 

[JimStanmore]

Overlord, those were my thoughts exactly. I have quite a bit of liquid (stocking up) that I bought before I discovered the KR808. Now I have bought a bunch of cartomizers. I'm hoping I can stretch them out past the burnt taste/throw out sequence. Now I am working on the right amount of filter material to use. I am getting about an hour of heavy vaping compared to the two hours of a prefilled.

Here are some images of where I am at so far:

Really interesting. Thanks, Jim. I will have to try this; wish I hadn't thrown out some dead cartos the other day.

 

[JimStanmore]

Be careful about jiggling the tube around too much. One of the three I have done so far has a very hard draw from that. The same thing happened to a prefilled when I refilled it.

 

[Overlord]

Thanks for the images. Really simple concept once one thinks about it. But we all really appreciate the work you're putting into this.

Have you tried any other filler besides the fluval or polly fill?

High Temperature, Heat and Flame Resistant & Thermal Insulating Fiberglass Knitted Sleeve

Why has no one tried Fiberglass Sleeving? It seems to me that it would eliminate any burning issues associated with the original material in the cartos. I have used silica rope to replace the metal wicking in regular atties.

I really wouldn't feel comfortable having fibreglass in my carts.

.... although i think thats what the wick is on the 510's. Ignorance is bliss in that case lol

It would be cool to see if nomex or kevlar come in fibers big enough so that it isn't like packing a carto with asbestos.

 

[JimStanmore]

There is actually a sleeve around the atomizer between the batting and atomizer. I need to look more closely at what that is because I am finding that it has an impact on the flavor. If I leave a burnt sleeve in after replacing the filler/batting, there is still a burnt taste. Replacing the filler preemptively (before the cartomizer "fails") there is a good taste. Leaving the sleeve out seems to affect the wicking. There were about 8 to 12 810-style big clouds of vapor vapes and then the flavor drop off.

Tonight I will be trying polyfil and "fluffy" Fluval. A roll of PTB also seems intriguing...

I tried the fluval today, my 1st time for my rn4072..

only my fluval isnt the soft batting kind? its more like a firm sponge?

is it ok to be using the firmer foam of fluval? tia

 

[AlexTM]

Should not be a problem, although I don't have that one, so I can't say for sure. I use this material with great success in my 510/901.

 

[JimStanmore]

Tia, If you look at the picture you will see I am using the firmer fluval. This is all experimental anyway, so you can try any of the cart mods that strike your fancy. In my other PVs I started with PTB (Pyramid Te Bag) and then the polyfil. After trying the fluffy fluval I switched to the more rigid type and that is what I have stayed with. It lets me use thicker (VG) liquid in my 801. I tried it in the cartomizer first because it is easy to slip it in between the wall and the atomizer.

My next experiment is going to be using a stirrer as a core and wrap one layer of heavy fluval and then a few layers of fluffy fluval. Then I will slip the stirrer over the atomizer and slide the filler package into the cartridge. Similar to what I imagine the manufacturing machine does.

 

[imawitch]

so far im really liking the firm sponge fluval..

yeah, its working ok for me, much better than the pollyfill,jmho

 

[Cielo]

I have ptb in my pantry, my daughter loves the tea! I have a few older cartz (none are dead) that I simply stopped using because they turned brown even after cleaning. I might try the ptb one and thanks for the pics.

Jimstanmore,

I use an 801 on my GGT and my Silver Bullet and vape at 5-6v, I have been playing with something like you are stating in your last post and having some luck with it.
