Do I need to hydrotest tuxing bottle in 3 or 5 years, Do they even hydrotest non DOT bottles Im new to pcp airguns.

I bought a tuxing 6.8 liter bottle from amazon for $297 https://www.amazon.com/dp/B09CPRRLGY?psc=1&ref=ppx_yo2ov_dt_b_product_details it says manufacture date 9/22 so in 9/25 should I hydro or wait 5 whole years it says retest period 3 years but I see some people dont worry about hydro for 5 years on these bottles, Im not trying to go out like a taliban in my room an have my arm shoot thru the neghbors window.

The dive shop closest to me will refill any tank that is within the 15 year time frame from the marked manufactured date which I was actually quite surprised but also pleased to hear.

That is great! The ones I contacted were all paranoid, even after I sent them the regs where it states it's ok.

FYI, those Chinese (and Korean) bottles fall under the ISO standard, which is more stringent than the US DOT standard. The US DOT actually acknowledges this but dive shops and the like shy away from accepting and filling ISO bottles because they don't understand that aspect of the rule and have the, "better safe than sorry", attitude.

Did not know that, Great to hear.

very informative,I have heard and seen the damage caused by high-pressure air,one a life boat bottle flying through a wall, and the craziest, the explosion of an earth mover tire being overfilled until it exploded,it was not in a cage and caused a fatality.
Hand Pumping a bottle to 4500psi,....oh my, Hercules Cortez

those cheap Amazon bottles... I like not thinking about being blown up I just gas my guns up with a compressor and decided to not mess with any of the big tanks. With my guns having a fill pressure of 300 bar and I like filling them to that level, the bottles are almost useless anyway. 185 shots is a lot and if I need more ill just purchase another 300bar bottle and swap it out on the rifle.
