Hot-dip galvanizing offers excellent durability and corrosion protection for steel scuba tanks. However, the hot-dipped galvanized finish is "industrial grade", with noticeable cosmetic imperfections. While the cosmetics of hot-dip galvanized scuba cylinders in no way impacts their durability or function, your complete satisfaction is our goal so please consider carefully before purchase.

We also include tank boots on the steel tanks for use when setup as singles, but boots are not normally installed on doubles sets and therefore not illustrated in our photos. The cylinders each have a current month Nitrox Ready decal and depending on shipping restrictions normally arrive with modular valves and plugs installed, ready-to-use as independent single cylinders and ready-to-assemble as doubles. Assembling a set of doubles is easy if you follow the detailed instructions we provide.

  • Aluminum tanks versus steel tanks
  • Tank paints, coatings, and finishes
  • Tank dimensions and capacity recommendations

SCUBA Tanks must be hydrostatically tested every five years (60 months). We always ship Faber cylinders with a current hydro test date. Due to manufacturing and import cycles, the popular sizes of Faber cylinders typically have a factory hydro date less than 12 months old. However less popular sizes of Faber cylinders may have a factory hydro date up to 24 months old as these are manufactured and imported 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.
