Dive Gear Express ships your Nitrox Ready cylinder with the valve installed (domestic ground US only). Unless you select no valve, the valve included in our price is a very high quality DGX Premium Pro Valve in your choice of design, plus a DIN/K insert to make the valve suitable for use with both DIN or Yoke regulator fittings. The cylinders ordered with valves have a current month Nitrox Ready decal.

Our "DGX Complete" Setup Includes:

  • Nitrox Ready Cylinder
  • DGX Premium Pro Valve in choice of design and configuration
  • DIN/K Insert for use with Yoke regulator fittings
  • Spare O-ring for valve face
  • Valve Protector Cap
  • Current Nitrox Ready Decal †

† Our shop evidence of inspection 3" X 6" dated decal (aka "VIP sticker") states "this cylinder and valve are suitable for service with compressed gases containing greater than 23.5% oxygen." That means the cylinder and valve, prior to initial use, are oxygen clean and oxygen compatible. If you plan to use this cylinder with gases containing more than 40% oxygen then the upgrade to our DGX Premium Oxygen Valve is suggested. If you select the No Valve / No VIP option, then the VIP decal is NOT included.

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

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. Cylinders are NOT marked appropriately for use in Australia and New Zealand.
