Can someone please educate me regarding what adaptor is needed to fill this tank? I went to a dive shop and they said they don’t know how to fill this type of valve. Thanks in advance for any advice.
Filling Omega tank with Hp3 valve?

You might need a female DIN to 1/8 Foster adaptor. or you could try a paintball place, their valves are filled the same way. I'm surprised that the dive shop doesn't have something that will work.

It would be interested to hear any and all re this. I got an upgraded tank from AoA for my baby Omega but honestly don't know what that means or how it matters or what to do next. This is a very weird hobby, with obviously a huge learning curve.

Most dive shops can fill through a male Foster fitting. So if you have a fill system with a female Foster, get a male to male fittingly ng.

No, one gauge. I got it with the "HP3 upgrade" and the "300 DIN female to female QC fitting."
There is something else I should consider getting?

Unless I'm missing something above, you should be set. That adapter you bought should screw right onto the 300 DIN fill hose, and attach to your tank.
CHECKMARKSMAN, I don't know what rig you have, but I think this is all you'll need:

K thanks. Those two items plus the Omega 18 CF tank were the entirety of my order from Airguns of Arizona.

Sorry for the slow reply. I missed the post.
I believe that adapter posted above will fix your issue. You can call AoA to be sure, but they have been selling a lot of them as they have a stock pile of bottles in stock but no DIN hardware for them. I almost had to order one a few days ago.

You get your HP3 valve filled through the male Foster fitting that is the same spot you connect your fill hose to when filling your air rifles. If the dive shop doesn't have a female quick connect like your output hose has on both ends, you have them screw on the DIN300 female to Foster quick connect to their DIN300 fill hose that connects to scuba tanks. They snap on the female quick connect to your male foster fitting on the HP3 valve. They just open your top valve to fill your tank through this adapter. Most shops should have that adapter already. All paintball shops fill through a male foster like your tank has.

Well I took my Omega tank from Airguns of Arizona to the local dive shop to have it filled and it was pointed out that there was not enough glycerin in the gauge. The person helping me said that could lead to inaccurate readings. For whatever reason, I didn't look at the gauge again until it occurred to me that I should while I was still in town. So I see it reads 4000 PSI.
I called the shop and asked whether they really filled it to 4500 and it was just a faulty gauge. The gal said she remembers seeing their equipment confirming a 4500 PSI fill. So ... my gauge is off by 500 PSI. And my gun fills to 3000 PSI, so 500 is significant. I will get some glycerin and put it in the gauge; they said there's no danger involved in that simple operation. I guess I'll call AoA and ask exactly what kind or thickness or whatever is best, so I don't have different liquids in there. And I hope that fixes it!
Anyway, a teachable moment -- when you get your tank, have it filled professionally the first time so that if there is anything wrong, you'll be in the know.
For now, I will rely on the gauge in my airgun, though that's not ideal and will be a bit awkward.

If you get your tank filled to 4500, by the time you get home it will read about 4000 after it cools. Leave the tank overnight and have them top it off in the morning before you pick it up.

Ah, I hadn't thought of that! Thanks for the tip! Boy I'm learning something new every day here. It was definitely warm when I got it.

I hate to say this but that dive shop sounds like a bunch of clowns. The glycerin air bubble in your gauge causes inaccurate readings? That's total bull crap. 99.99% of gauges are filled to the same level as yours with a little air bubble in them. The only reason for having glycerin in a gauge is to make a gauge needle shake less when connected to machinery so it's easier to read. It has no other function and most certainly has nothing to do with the calibration of the gauge or its accuracy. You could have no glycerin at all and it won't affect the gauge's pressure reading. Glycerin isn't actually needed for SCBA tanks, it's just a common additive because many gauges are used in machines that vibrate, like dive compressors
On another subject, dive shops are notorious for providing hot fills. Their compressors fill fast and the heat built up shows 4500 psi so they shut their compressor down. If they are a good shop, they'll let your tank cool down at which time it will go back as far as 4000 psi. A reputable shop will then top off the tank to 4500 because filling a smaller amount won't heat your tank much during the top off. Your gauge is probably very accurate. It read 4000 psi after they filled it to 4500 because of the cool down.

Thanks for the info, Humdinger. In my smallish city, there's little or no competition for a lot of goods and services, so the quality tends to be very low compared to what you find in a big city. This is the only scuba shop in town ... so .... no surprise there ...
