26ci hpa tank tippmann 2024/11

Partially correct @rocketdogbert

 

There are now low capacity fibre wrapped 4500psi cylinders and those would not be exempt

 

Low capacity aluminum cylinders such as this or 13ci are valid for indefinite use in the UK

Provided they are UK legal in the first place, aluminum, rated for 3000psi,  within size, and don’t have contradictory markings 

 

In the US they call it the 2x2x2 rule

(What’s important there is 2” diameter, 2’ length)

and in the UK I haven’t paid for the full specs but defer to Trevor Kent of HPAC 

 

A problem you can come to is if the manufacturer has added contradictory markings and have painted ‘’Hydro test due = x”

If that’s showing then as a bottle checker it should be refused, but if the paint is worn leaving only the proper legal stamped birth date, specs etc then it’s good forever provided it passes a visual look over

 

 

 

Another little known fact is that aluminium 48ci 3000psis are valid for 10 years between hydro test in the UK but manufacturers often paint a due date of 5 years 

Different sites may enforce a 10 year or 5 year cycle on those

(With the cost of testing it’s not necessarily viable to bother for aluminium 3000s)
