Dry cell gasket
It has been a while since I posted, but I was hoping over the last few months people have had some experience with cell components.

My original design I used shower pan gasket that is .040 thick and doubled it. So my 8x8 cell spacing was .080. Maybe the gasket material was too hard, or there were simply too many seams running a double garsket but my cell continues to leak. I didn't really care since I have it mounted under the truck against the frame rail but I continuely have to add more water and electrolyte.

I am going to tear apart and rebuild it and I found this strip vinyl for dock doors where I did not have to buy a 100 yard bulk roll. Grainger had it where I could by 5 strips. Almost exactly what I need. These strips are .080 thick which is where I have been all this time with my current cell.

Grainger Part number: 3TA96

Has anybody else used this for their dry cell and what have your results been?

Here is when I originally built my cell but I had to double the gasket:

My cell is 5n6 that puts out 4 lpm

Rubber Sheet, that doesn't tell me much.
So what is it? What is it called? Where do you get it and under what name? And if you have a link, that would help too.
Thanks,

I just build my first dry cell using this material. It is Neoprene 3/32", 40A Durometer, Temp. Rating -20 to 170, 12"x36" for $11.75 + tax. It works!!
mrbillr where did you get those SS plates? Thanx for any info.

One thing is for sure, shower pan gaskets will eventually seep a bit, even with a lot of bolts. Good post.

So far it has helped over 2 mpg, or 15% improvement. It never does get very warm, since I run 5 neutral plates and everything is mounted underneath the truck along the frame rail. More air goes by there than if it were mounted in front of the radiator. Duration? that 2 mpg gain was during a 12 hr trip to Tulsa and back.

jbalat Wrote:4 lpm sounds like a lot for that unit.. What amps are you running ? how big is it ? Do you have any plans ?

Actually, 4lpm I could probably go even higher. This cell is huge.

It is 36 SS plates that are 8x8. It weighs about 25 pounds, so it is not a little glass jar contraption.

Here is the unit from my previous posts:
My Dry Cell

The initial post says it is 4 neutrals but I changed that up to 5 neutrals and all 36 plates.
It pulls between 40 and 50 amps. I have a 100amp constant ON solenoid to power it.
One of my observations when I tore it down was that the discolored line on the plates was only half way up. I theorized the HHO bubbles and pressure inside the cell were keeping the electrolyte from replenishing to the top.
I added a 1.5 gpm pump mounted on the bottom hole of the cell it to help flush the bubbles and maximize the electrolyte on the cells. It only draws 1 amp so nothing really lost by adding it, and everything to gain.

My brother's shop, he cut up some scrap and I just paid for his dinner on his business trip down Laugh

Gary Wrote:One thing is for sure, shower pan gaskets will eventually seep a bit, even with a lot of bolts.

And that was my problem, I continually had the white crusty stuff all over the bottom of the cell (dried Naoh)
And bolts, I have 16 total, 4 on each side, so I have lots of bolts and fender washers on each one to help distribute the pressure.

I have 3/4 plastic plates ordered and they should be here any day, then I will tear down and rebuild with the new gaskets (vinyl door curtain)

Thanks for the encouragement.

All being said, I have definitely seen mileage gains with HHO.
