New tank

After years with my tanks expired and nervous every time I recharge them

I decided to buy a new equipment, a 7L 300bar bottle made in the Czech Republic with CE certificate

I also bought a new Chinese charging station from Aliexpress recommended in another forum, the truth is that I am amazed by the quality and the low cost all in stainless steel and gauge with glycerin

Enkey, U.S. dive tanks use DIN300 connectors that are G 5/8 threaded just as yours is. I don't even know what INT thread refers to.

BTW, your fill adapter from Aliexpress is decent for the price, but their gauges are notoriously inaccurate. Do compare your readings to another gauge that you know is reliable. I got one and had to replace the gauge which was reading 400 psi or 28 bar lower than the actual pressure. 

Is your tank made of steel or aluminum? What is the weight of your 7L tank? Carbon fiber tanks outsell metal tanks 10 to 1 for airgunners in the U.S. because of their light weight and portability and 4500 psi or 310 bar fill capacity.
 
Hi Humdinger

Thank you very much for your clarification, the comments of some members here made me believe that in the U.S. another type of thread is used

If the gauges are always inaccurate the same as those of $ 2,000 airguns but I never fill my airguns to the maximum and with an approximate estimate is enough

The tank is made of steel and weighs 10kg much heavier than the aluminum ones but at the moment it is not a problem for me
