I am looking for a match to my newly acquired Faber/OMS LP46. Out of hydro is OK.
I have cash/paypal, an AL40, AL30, or an old 2250 psi 50'ish (6.9") tank that could be possible trades or trade + $.
Exchange in NFL is easiest for me.

Going after a little smaller passage eh? :D
Hehehe... no, mainly playing with gear. I figure it would be perfect for Buford though.
Hmmm. I have 5 "like new" Faber steel 72's 3300 psig (not the LP2650's) so you get twice the gas for the same length just 1" bigger around.
Not really. Twice 45 is 90, not 72. Besides the LP 45s will hold 60 cu ft, and the HP 72s can't get much more than 75 cu ft.Quote:

IMH, any steels are not appropriate for stages or deco bottles

Yep... my compressor is set to turn off at 5000 PSI no problem LOL..................
There all yours... just send me a check.
If they are so great, why are you selling them? :-DQuote:

I said LP 45s were great, I don't use HP tanks, too heavy for the little gas you get :roll:Quote:

Do the math!Quote:

Jason, I hope you are happy we are keeping your thread on top :-D
My Faber HP 133 has the same external dimensions as a Faber LP 108, but at 3600 psi it pretty much holds the same gas volume as an LP 95...
A LP tank hydros around 4500ish and a HP tank hydros at 5800ish. I have access to a compressor that fills to 6000, I could probably get away with filling my HP bottles to 4500 without doing much damage to them and I could hold around 160-170 cu ft in my 133s, but I don't because that would wear out my regs really fast and it would be illegal to transport them on a public road ;-)
Overfilling any LP tanks is illegal to fill and to transport.
So...for 7 cu/ft more gas, other than in cave country, you have to hassle with getting anything more than 95 cu/ft of gas with illegal fills.... Most of the time you will get a 2650 fill than will could to say 2450 psig or 2500 psig so you have less gas than even 95 cu/ft. At least with the 117, after cooling one has more than that. Am I seeing this correctly? It just seems that the only way that there is any positives to a LP is if you always what to be purposely, and illegally, over filling the tank, and to do that one has to either have their own fill station and always use it to fill, or always fill or dive in cave country. Seems that for 7 cu/ft of gas it is ridiculous to purposely over fill a tank, all legalities, risk, and liability aside, and then have to hassle with it every where else you go except cave country? BTW.... I have several sets of both, but still do not really see the point in LP tanks except for O2 bottles or if one has to PP fill which is why LP tanks came into vouge in the first place when we all started 25 years ago. If I want less gas than 117 I can just under fill, legitimately. Just trying to see if I'm missing something here.
There is someplace else to dive? :roll:Quote:

Yes, the only thing to be learned here is that the American method of naming tanks leaves a lot to be desired. The European method (internal volume) makes it a lot easier to tell how big a tank actually is.Quote:

Look at regulation 173.301(e) : o(
I don't see that paragraph?? Besides those regs apply to interstate shipping, not individuals with tanks in their own truck/trunk.Quote:

I wasn't so much looking at shipping as filling. The above section is specific to the preparation of compressed gases. Either way it is a mostly an academic argument as it is not enforced.
Considering the fact that 3442 psi "HP" tanks are re-rated LP tanks makes the previous discussion pointless as Forrest pointed out. Who fills their tanks to 3442 psi anyway??? At least Jason is getting the all bumps from this.....
The PST tanks are not just re-rated. The internal volume is less, probably because the walls are a little thicker. You may be right about Fabers, though.Quote:

I do appreciate the bumps, btw :)
I've got one. Origional hydo was 02/08. It's yours for 150.00
Send me a PM if intersted. PayPal is fine.
