3k psi Fiber Wrapped Tanks - Who still makes them?

[Surf2Live]

Is anyone still making 3k psi fiber wrapped tanks? I've got a couple of older Air America 3k bottle regs that I'd like to put back into service and would prefer to save some weight over the current aluminum tanks.

I'm ok to mount a 4500 psi tank on them and only fill them from the 3k whip at the field, but that option may not fly with some staff depending on, 1) who is checking tank hydro that day, 2) if they know what they are looking at, and 3) if they believe I'm actually smart enough to not use the wrong fill station. I understand it's an insurance/liability issue for the field to allow mismatched bottles and regs and that rules are rules. I'm not intentionally trying to do anything hazardous; just want to use some old equipment.

Thanks!

I haven't seen any in years, if the production methods are the same there really is no point to produce a 3k over a 4.5k

You are in the extremely rare position of wanting to use a specific regulator regardless of what tank it's on

Hmm, isnt the point of different burst disks for 3k and 4.5k regs make this essentially moot?
If you use a 3k reg with a 4.5k bottle, the burst disks should be correct for the reg. So if you attempt to overfill you would pop the high pressure burst disk.

Does that make sense? Did I get that close to correct?

I totally understand the desire and importance of having the correct matching parts, but just trying to illustrate the safety of the situation if you have a memory lapse when filling.

I mean you are not wrong, the problem is nobody looks at the burst disks when filling. They just look at the side of the tank. It's like saying, "my car has an airbag so getting in a crash is safe" while probably true, you just don't want to test that every time you go drive.

That aside if I were surf, I'd absolutely just grab a 4.5 tank and throw his favorite regulator on it and just be responsible at the field and tell them to only fill to 3k

I would however also bring a second tank just in case they have any problem with this

What size tank are you looking for surf?

I understand what you mean. My point was do exactly as you said, but in the worst case scenario if someone tried to fill it to 4.5k, wouldn't the burst disk pop?

Oh wait, aren't 3k reg high side burst disks rated at 5k? If that's the case, scratch my thought process

It’s the same as filling a metal 3k bottle to 3k instead of 4500

you just tell the person to fill it to 3k

i have never been in a situation where I’m separated from my tank in a way that I’d be concerned and the technicians filling tanks are just as interested as you are to not blow up.

The regs are indeed designed to not fail catastrophically in an overfill situation.

If they made 45/3k wrapped tanks that were even an ounce lighter than a 45/4500sl2 tank I would use it because I basically never ever get fills over 3k because of the fields I play. Unfortunately such a thing doesn’t exist

My local field has mostly alleviated issues like this by having the outdoor fill stations only go to 3000psi max. Anyone who wants a 4500 fill has to go into the shop and an employee will fill it behind the counter.

That’s a nice idea. When they just have random barely marked fill whips and one goes to 4500 and the other to 3k I get a little sketched out when I see goofballs filling their marginal tanks

-Ditto. I've got at least half a dozen AGD Flatlines that I'd love to keep using, but they're all long since expired.

Now, I can fill them myself from a number of sources, but obviously that's not terribly kosher. I don't put a lot of use on any of my tanks, so they're probably okay, but it's still not cool.

Somebody was making round-bottom 3K aluminum tanks, but they were 48s rather than 68s and would be too stubby for the Flatline drop-forward mounts.

Doc.

I've got a Flatline on my classic RF mag that I'd love to use but I've got the same issue. The arms of a 6'3" tall player don't work well with short tanks.

Thank you everyone for your comments. I was 99% certain that nobody was making them any longer. I'm comfortable with knowing that I won't accidentally use the incorrect whip and the fields I play at don't fill tanks for you if you aren't renting; but, they do check hydro dates and I've been prevented from filling an "out of hydro" 13/3000 by an employee one weekend because the '2x2 rule isn't real' and then was allowed to fill it another weekend by a different employee. Trying to avoid not being able to use a marker because of someone's uncertainty.

The reg in question is an AA Raptor so not being allowed to use the tank means in order to use the marker I would have to swap the reg specific cradle for a regular screw-in ASA and add an inline reg to knock input pressure down. At that point I'm almost rebuilding a marker in the parking lot at the expense of play time and I'd just switch to a different marker for the day to save the hassle.

Guess I'll look for a cheap 68/45 bottle with some life left on it, take my chances at the field, and bring a couple spare markers like usual.

You can get 3kpsi aluminum tank and have an OK time.

I could... but at risk of sounding like weenie, the marker/reg combo already weighs ~6 lbs without a tank, hopper, or paint and a 48/3k weighs nearly 3 lbs and is too short for my long arms.

scottieb GET OUT OF MY HEAD!!! I meant... there's a fair amount of stainless; pretty much everything except the body, frame, and internals.
