Carbon fiber tank from Ali
Is it safe to use carbon fiber tanks and valves from aliexpress?
I ordered these two but I`m not shure if it is safe to use or if I should send them for pressuretest first.

meech, lovin’ that setup. What valve is that? What threads are they? Love the Wika gauge. I just went cheap with my acecare bottle/valve package (separate brand fill whip with gauge) because I liked having the built-in tank pressure gauge as it tells pressure at all times. I didn’t want to have to use a dead head to check pressure.
nice. i am looking at building some similar setups.
Here are the tank, fill valve, and both. I’m planning on adding QC fittings on the other end next to the gauge so I can remove the hose for easier storage in my back pack. The quality of the tank is great. I need to top off my bigger tank first and then I will fill the small tank. The total length from top of valve to bottom of the tank is 14.5 inches. I plan on using this set up to fill my Leshiy when I go shooting in the field. Scoped Leshiy, tank will go in my Tasmanian Tiger Essential Pack and pellets, hose, knives, flashlight, and other essentials will go in a TT Tac bag 7 attached to the TT essential pack. It is inconspicuous and comfortable to carry. I will take a pic of my gear when I receive the TAc bag and Quick fill connectors.
thanks for looking in,

2.17 liter tank with CaseLogic case. Then those placed inside my Oakley backpack.
I got my mini valve from Best Fitting today. I love the quality and small size! Waiting for my 0.5 L cf bottle from Ali to arrive now.
Question for Cricket or anyone else who has a mini valve: Are you using a Quick Connect fitting with or without a air flow restrictor? I have a fitting (from Best) with the ability to remove the restrictor. Opinions are appreciated!
Thanks!

I bought an Aliexpress 3 liter tank, Aliexpress fill valve, and a DIN 300 fill assembly. I fill all with my own compressor. The tank and accessories are all of high quality and I’m very satisfied with the purchase. I haven’t seen any Aliexpress carbon fiber tanks that had other than 18 x 1.5 neck thread. All of the fill valves I’ve seen fit this thread type. If there are others such as 7/8″ x 14 UNF I haven’t found them.
Thanks Cricket
Got my Ali tank and Best fittings. Just realized I can’t see tank and fill pressure.
Cricket, did you add any teflon tape to threads or just tighten everything hand tight?
No Idea, I just got a 300 bar tank pressure tested to 500 bar. I fill it myself so “DOT” and such markings do not concern me much. I have filled mine to 300 bar a number of times and have no issues with it so it does exactly what I want it to
Any difference in pressure rating from the M18 x 1.5mm vs the M25x2mm? The Ali tanks come in both.
I assume all DOT tanks are UNF.
I was going to go Ninja PB tank w their PCP reg, but they limit to 3k output.
thanks

Yup I must haves messed something up. Thanks
Then you probably did something wrong. I get 2,3 fills with these stats:

I used the airguns of Arizona calculator. But with it it shows I couldn’t top off my condor at all from 2800psi to 3500. That didn’t seem right to me with a 1.1l tank.
Unfortunately I’m not very good at “taking notes” on such things, I just roll with it so I honestly can’t say. But there is a great calculator here https://sye.dk/airgun/. I have used it with a Cricket compact once and my Leshiy. For the Leshiy it works great, and with the Cricket I can attach a longer hose and tether the gun for a looooot of shots when target shooting. But I mostly just top it off until the pressure is too low. I usually get bored before the air runs out but that’s not much help to you I’m afraid.
Cricket. What are you using that 1.1l tank to top off? How many top offs does it give you?

Biz,
M18 x 1.5mm thread pattern.
Here is where I got it from:

Including air mail w/shipping to CA from England, the valve set up , a quick fill female fitting, a dead head, and dowdy seals, it cost me $130. The tank was another $103 shipped. I think this is a good deal for brand new stuff. In my case, I was looking for a small set up that I can carry in the field along with my Leshiy in a small pack. Oh yeah, I got every thing one week after I ordered. I was surprised when the tank show up yesterday. This is the pack I bought:
