How much for just the tanks with Plugs. Dont need the Valve.
Thanks
minus 10 bucks
Two for 500.00?

No, sorry... they sell quick where they are at. But I can deliver to cave country and save you shipping.
You can probably make up the difference selling the valves.Quote:

Yes, rated to 2640. I routinely put 4k in mine. I just bought a set for sidemount for me. At 3600psi they hold 116cu'
That is impressive at 4k you have tanks slightly larger than an al 80 that will give you 257 cubic feet of gas. Using two obviously

Yeah, I did grand traverse at Peacock recently and never hit 1/3rds.
I'll get a set someday

Faber FX100 = 787 Cubic in
Faber LP85 = 793 Cubic in
Difference = 6 Cubic in = 0,00756% volume in water
if you take it at 237 bar it mean 1.79% more gas at rated capacity
How a diffecrnce in internal volume of 0,00756% end up with a 16% more gas?
Not sure where you got your numbers, but if it holds exactly 85 cubic feet at 2640, it holds 115.91 cubic feet at 3600.Quote:

There Smaller in size than an Aluminum 80. I have 8 of these myself and they are great SM tanks.
Size of tanks/working psi*100= how much cubic feet your tanks will holdper 100psi.Quote:

3.21*35=112
112*2=224cubic feet for a set of lp 85's filled to 3500
A set of hp 100's filled to 3500psi is 200cubic feet
So you get an additional 24 cubic feet. Not to mention if you can only fill them to 3k. Which some shops will only do, then you are better off with the lp 85's
Or
85 / 2640 x 3600 = 115.9
figure RN showed me the complicated way....
Hydro date?Quote:

I know the math it is not the problem, how 2 tank with the same internal water volume can have such a big difference of gas capacité at the same pressure? The math use here are an APPROXIMATION the gas have a compressivity factor at these pressure p1v1=p2v2 dosn't apply directly at the pressure in question. Ã#
For me 2 tank with the same water volume will always have the same quantity of gas of the pressure is the same.
Um, they are BRAND NEW... so like last couple months. That haven't even arrived from Blue Steel yet... definitely late 2011
The math is not the problem, but it proves there is something wrong with your quoted "water volume" figures. Where did you get them?Quote:

This statement is true for me (and everyone else since it is a basic law of chemistry). The number of moles of an ideal gas are given by n = PV/RT (where R is a constant), so two cylinders of the same volume that are at the same temperature and pressure they will have the same amount of gas.Quote:

If I recall the 85s are filled way above their rated capacity to 3600psi, while the 100s are only filled to their rated capacity, which is 3500 (or 3442) psi. I have not checked your volumes for accuracy, but I know that the two tanks do have different volumes.
The HP100 seems to be an LP80, not an LP85.

If you dropped an HP100 to 2640, you would not have 85cu'. You would have 77cu'
If you pushed an LP85 to 3442 you wouldn't have an HP100. You would have 110.82cu'
The internal volumes can NOT be the same.
Interested in a pair - how do I contact you? - do you take plastic?

Yes I take plastic.
From Faber, internal water volume:
Faber FX100 = 787 Cubic in
Faber LP85 = 793 Cubic in
Difference = 6 Cubic in = 0,00756% volume in water
Close enough to be the same volume for me if you take in fonction the manufacturing tolerence, the HP100 can be bigger
p1v1=p2v2 is not linear at these pressure it can not be apply directly
Ok, so the pallet of tanks arrived today. I managed to ship all of them out except two. Original Hydro is 05/11. Let me know if you need a tank or two. :)
