    As always delivery was fast but the best part was the tank came with a current VIP sticker so no need to take it to a shop for visual inspection.

    Perfect

    Not much to say about a 6cf AL cylinder. It works perfectly as a drysuit inflator bottle. It came with the valve installed and a VIP sticker in a bag that I could apply or not, as I chose. This plus the DGX drysuit inflator reg gave me everything I needed for my drysuit for $190. Can't beat it! 50 cents worth of bungee cord to mount it on my BP and I am good to go!

from Dive Gear Express

  • 0.750-14 NPS (3/4 NPS) threaded neck opening

How to Select a SCUBA Tank

Our factual but easy-to-read article helps you make this big decision by giving you information on:

  • Aluminum tanks versus steel tanks
  • Low-pressure tanks versus high-pressure tanks
  • Tank paints, coatings, and finishes
  • Tank dimensions and capacity recommendations

Click Here to read How to Select a SCUBA Tank.

SCUBA Tanks must be hydrostatically tested every five years (60 months). The larger primary cylinders typically have a factory hydro date between 3 and 9 months old, but not more than 12 months old. Smaller cylinders may have a factory hydro date up to 24 months old as these are manufactured less frequently.

Our cylinders and valves are Imperial 3/4 NPS neck threads, NOT Metric M25 neck threads, and the valves have overpressure relief devices. The cylinders have US DOT and Canadian CTC markings suitable for use ONLY in North America. Our cylinders and valves are NOT CE approved and NOT suitable for use in the European Union, and NOT marked appropriately for use in Australia and New Zealand.
