Would these tanks work?

Yeah. That's a DIN valve. Gotta have them in hydro if you want to be able to have them filled. If you fill. Yeah. No problem.

They appear to be 45-minute Scott SBA tanks. the specifications printed onto tanks will give maximum service pressure, size, date, etc.
I had a 45-minute which was filled to 4500 PSI and worked well. Mine was over date but I didn't care because I was trained in their use (fire dept) and understood their construction. I filled mine by a series of Yong Heng and YH clones. I eventually gave up on the Yong Hengs, and found that a GX CS3 compressor was much more convenient, because it was about the same size and bulk but direct filling of my guns was more convenient.
We shoot for 6-7 hours, almost continually during each week's range day, so use a lot of air. It required 1/2 hour for my YH to fill from 3,000-4,500 PSI. It may be useful to consult a calculator to estimate how many fills of your gun(s) are available from the tank.
OTOH, the tanks is quieter, potato/potato.
You will need a fill station such as this, but you already know that, right?
Tank thread CGA347 (if same as Scott) ¾-16. Valve outlet for CGA347 probe and nut 7/8-14 TPI.

All my tanks are used scott scba tanks. One has a current certification the others are all expired. I remove the valves and replace them with a pcp valve. Scott tanks have a 7/8-14 thread. I would assume all usa made tanks have the same thread

Replace your factory tank valve with our larger, more efficient valve. The large knobs and handle make filling and releasing air a breeze, providing enhanced control and ease of use for just $200

I have one of these as well that is in really good shape. Ive had it a long time. Way out of date. Has a brass adaptor from China to use normal pcp fill valve threads, and a bisley valve from best fittings. I think i paid around $75 for the tank. But I assume it'd be worth more if it wasnt too old to be hydro'd

I also use an expired Scott airpak, 45 minute, which I fill with my YH. I use the stock valve but I took the spring out of the stock knob so there is no impediment to rotation of the valve. I ended up buying a somewhat expensive fill set from Air Tanks Plus which works great. But I wonder sometimes if getting a Chinese bottle that comes with a fill set might not be a cheaper way to go. I suspect the Scott bottle is better made, however.

Did you know you don't have to remove the spring if you just tighten the nut in the center of the valve knob all the way down? It compresses the spring past the safety lock feature. All 4 of my tanks are Scotts (15, 30, 45 & 60 minute). Valves are very simple & robust & cheap to replace if needed.

The Standard Scott valves (not quick connect but threaded) require a CGA347 fill adapter, not a DIN.

Thank you for honoring me with you exclamatory correction.
Boy am i so wrong. Punish me gerry. Report me too!
Cga 347
What's this. This the one with resolution good enough to see?

No, I did mean that the standard valve on a Scott tank needs a CGA347 adapter.
I'm assuming your reply to me was meant to be humorous. Only reason for my exclamation point was so OP didn't follow incorrect information, not to "punish"
you. I'm not your Daddy
. Just seen too many times when people unfamiliar with equipment were sent down the wrong road. The picture you show is a DIN HOWEVER it's not a STANDARD Scott valve like the OP was showing. Get it? Upvote 0
Also do understand that the typical service life is 15 YEARS from labeled date of manufacture. Commercial / Retail etc HP filling facilities WILL NOT fill post 15 year life .... or will they fill a time legal tank IF THE 5 YEAR HYDRO TEST interval from last test has expired.
What we do at home with our own compressors does not apply, as we take liability for any such action.

I assumed most bottles 300/310b bottles had a din300 or the 7/8-14 "stub" which would then have a secondary valve and din300 or adapter to 8mil foster. I had no idea that was called cga347.No, I did mean that the standard valve on a Scott tank needs a CGA347 adapter.

My dräger and acecare have those little outlet stubs both lead to din 300 adapter

CGA347 was on most SCBA tanks as fire authorities were trying to standardize fittings for firefighting equipment. DIN was usually associated with diving equipment (SCUBA) but we airgunners use a bastardization of whatever we can make work for us. I like staying with scba stuff & its inherent robustness. With the cga347 no secondary valve is needed, just the tank valve & cga fill adapter for airing up. They're fairly inexpensive too.

I have one of the direct fittings on the dräger. The acecare people.complicated it. Thanks for clarity. And yes thats my humor earlier.

Half of them have bad valves. They are all threaded and do not fit our newer packs. I've been full time FF for 20+. It's a good short term air source while I gear up.

I've never heard of that before. I'll be trying that out soon. What valve would you recommend for a replacement?
I see the valve now.
