Others DOT Certified Bottles?

[Hylander]

Looking at add on bottles about 500cc
Like the Tuxing. They say Not DOT certified.
Does it matter?
And what is DOT certified for an air tank?

DOT is one of 3 standards for test and inspection of CF tanks. It is the US standard.

CE is the European standard

GB is the Chinese standard

The only real difference stateside is if you want your tank filled at a shop. Then it has to be DOT. CE & GB tanks are 75% cheaper and made in the same plant just not as extensively tested. Not less rigorous, just less extensively.

There is no difference safety wise. It is just the US standard requires more time and steps.

I am sure there will be someone along to declare they only buy DOT. Which is their prerogative. There is no evidence that DOT tanks are in any way safer than CE or GB. The idea that the Europeans would allow their citizens to be less safe is ludicrous.

Thank you.
Just wanted to make sure a Tuxing bottle was safe to use. They are a good price on Amazon.

Tuxing, Alsafe, Acecare are generally considered the best. Tuxing and Alsafe are essentially the same company.

Thanks,
So Tuxing ok for rifle mounted bottles.
But for a refill tank, DOT Certified, so I can get it filled at a Dive shop, correct?

Yes, but the difference in cost for a DOT tank vs CE tank may be the cost of a compressor that can fill the tank at home. Then there is the time and expense of filling at a dive shop.

Amazon (with valve)
6.8l CE $256
6.8l DOT $457

AliExpress
Tuxing TXEDM042 compressor $412

DOT is ***North American Standard***...don't forget us lame Canadians
And I completely agree, Non DOT means almost nothing if your filling them yourself other than that it'll cost you less to buy. Buy the tuxing or equivalent, abide by max fill pressure (or even fill a little less) fill with dry air, and shoot on
Maybe use the money you just saved on pellets?!
Bought my Hill compressor for same cost as 2 decent sized DOT tanks and whips.....wise choice i think.

I've got four of them on different rifles and all are still working great.
