Got my first tank - question re: date stamp on it

That would the.born on date. 

Agreed

Yes, that is the date of manufacture. Your tank will need a "Hydro test" every 5 years. Use a reputable company and expect to pay around $35-50. 

Tom

That's the date of manufacture. It will require Hydrotesting in October of 2024. Hydrotest should cost around $30-$40.

I bought 4 60 min tanks on eBay cheap . Looked like new in condition. Took them to my local dive shop who filled them several times over and sold me $200 worth of fill stamps for a savings at the end of course. 

But then I droped two tanks off for filling and they wanted to Hydro test them $35 per 

Then informed me that they are old out dated Born on 2002 Hydro tested once befor and they will not fill them anymore. 

So here is the Question . 

Just orderd a day-state Compressor $2000 bucks. 

This is after Burning up in first week Nomad 2 

Then Killed a Hatsan in almost same time frame the bigger one. 

Both refunded at Pyramid air. 

But Back to the question at hand .

Should I be scared to fill thease tanks when the compressor arives ? 

Is this born on date another Dot or government way to make fire departments get new with tax payers money or I'm i going to explode and kill myself ? 

Thanks for any advice on this ...

Brought me to another ? Do guns with bottles or even guns with perminent air resavors expire as well ?
