2013 Agility NGV2-07 Individual Tank

Is this ASME or DOT rated, and what does that allow me to do with it?

This is a DOT-rated NGV2 cylinder, designed and certified for compressed natural gas fuel service on vehicles. DOT NGV cylinders are highway-legal for mobile fuel storage and cannot be repurposed for stationary storage or other gases without violating their certification.

What is the MAWP and capacity at service pressure?

The service pressure is 3,600 PSIG with a capacity of 40 GGE (gallons gasoline equivalent). The listing does not state the MAWP separately from service pressure; ask the seller for the nameplate MAWP and whether these cylinders were filled to 3,600 PSI working pressure or a higher rated pressure with a lower service fill.

What is the requalification or inspection status?

The listing does not provide requalification or current inspection status. DOT NGV2 cylinders typically require visual inspection every three years and may have a 15- or 20-year service life depending on the specific DOT exemption or special permit under which they were manufactured; ask the seller for the last inspection date, the DOT exemption number, and the manufacture date stamped on each cylinder.

What should I inspect before putting it into service?

Inspect the carbon fiber overwrap for impact damage, abrasion, cuts, or delamination—cosmetic damage to the protective cover is noted, but the structural composite layer underneath must be intact. Check the mounting brackets and hardware for fatigue cracks, verify all valves and PRDs are within their service life, and confirm the cylinders have not exceeded their DOT-mandated service life or inspection interval before refilling.
