We have a number of HP Steel 80s but there are times as an air hog I needed some extra time - these 120s fit the bill perfectly. They arrived, ready to be filled.

Questions and Answers for XS Scuba 120 Cubic Foot High Pressure Steel Tank:


  • Jim:

    there appear to be 2 manufacturers of high pressure steel tanks, faber and worthington. Is there a difference between the two other than price. Faber tanks seem to run about $40 cheaper

    Darrick  (Certified Scuba Instructor at Scuba.com):

    Hello Jim, Faber paint there tanks white, while XS Scuba will dip them in a Chromemoly Steel to help with the strength-to-weight resilience. That is why the XS Scuba tank run a little more. If you would like to place an order or have any other questions please feel free to give us a call at 1.800.347.2822.

  • Tom:

    When empty,how many cubic feet do they contain?

    Bob  (Certified Scuba Instructor at Scuba.com):

    When it's empty it contains no air at all.

  • Henry:

    At the surface about how many the breaths would you get?

    Bob  (Certified Scuba Instructor at Scuba.com):

    There is no way to accurately answer that question.

  • ajit:

    Does it includes nitrox sticker, i saw it says nitrox ready, i need to know do i need to order nitrox sticker too.

    Darrick  (Certified Scuba Instructor at Scuba.com):

    Hello Ajit, no it does not come with the Nitrox sticker. That is a separate items.

  • Joe:

    Are the tanks also given a fresh "hydostatic" test prior to shipping? Any guarantee that there is at least 4 to 5 years left before another hydrostatic test is needed? Also, is "Nitrox Ready" mean "O2 cleaned" or is that something that needs to be done after purchasing the tanks?

    Darrick  (Certified Scuba Instructor at Scuba.com):

    Hello Joe, you are looking at around a few months after Hydrostatic testing. If you would like to place an order or have any other questions please feel free to give us a call at 1.800.347.2822.

  • jody:

    i was looking at buying a couple of the steel 120 tanks and the biggest issue i was worried about is this i plan to use the tanks for nitrox and the my LDS uses partial pressure blending so are these tanks o2 cleaned or will the i have to get them o2 cleaned prior to use or is that the dive shops call.

    Darrick  (Certified Scuba Instructor at Scuba.com):

    Hello Jody, Yes these tanks are rated to 40% Nitrox Ready. But since we do not Nitrox inspect them. Your LDS might need to inspect them and they would put on your Nitrox sticker.

  • Ron:

    do these tanks have removable s for either din or lp filling and or diving?

    Bob  (Certified Scuba Instructor at Scuba.com):

    What you are referring to is called a Pro Valve, and yes, this cylinder does come equipped with one.

  • Adam:

    Has Worthington ceased manufacturing steel cylinders yet, or is the rumor of them closing their CA factory untrue?

    Darrick  (Certified Scuba Instructor at Scuba.com):

    Hello Adam, we have not heard anything of that nature from the manufacture yet about this. You would need to contact the manufacture directly about that.

Designed in 2004 by XS Scuba, these hot-dip galvanized cylinders are manufactured in North America by Worthington Cylinders. The Worthington Cylinders Corp. is already the world's largest supplier of industrial steel cylinders, and has become the market leader.

There are two different 'Series' of steel cylinders available. The most popular are high-pressure X-Series™ cylinders, as they offer the most air in the smallest size cylinders. The other are the low-pressure LP-Series™ cylinders which offer lower fill pressures, making them ideal for dive boats and many air compressors.
The exterior of all XS Scuba steel cylinders are hot dip galvanized. This highly demanded and preferred finish is utilized on all Worthington steel cylinders offered by XS Scuba. Don't be misled by claims from companies distributing steel cylinders with painted exteriors. There is no better process to protect a steel cylinder from rust and corrosion than hot dip galvanization!

Manufacturing Process
Built from Chromium Molybdenum steel plate
Utilizes the deep draw process; the preferred method to build a steel scuba cylinder
This process yields a cylinder with a very uniform wall thickness resulting in a lighter, more efficient cylinder
Buoyancy
Superior buoyancy characteristics (Specs)
These cylinders have been designed to be slightly negative at the end of a dive
Exterior Finish
Hot dip galvanized - the absolute best finish for a steel scuba cylinder
Nitrox Ready
Cleaned and sealed at the factory
Free of hydrocarbons to a level of 40 mg per square meter
Boots
Included with all XS Scuba steel cylinders
Quality, self-draining design

Valves

All XS Scuba steel cylinders include an International DIN Yoke valve
Allows upgrade to Modular valves and manifolds
Convertible design allows for standard yoke or 230 bar DIN connections
Standard inlet thread (3/4'-14 NPSM) on cylinder allows upgrade to any other Thermo valve
These valves are clean for Nitrox up to 40% FO2

Manufacturing Process
Our steel cylinders are manufactured at Worthington Cylinder's state of the art facility in Tilbury, Canada. The cylinders are manufactured using the Deep Draw and Ironing (DDI) process. Cylinders start from a circular plate of chrome-moly steel. Multiple draws on a hydraulic press transform the plate into an open ended shell. The shell is then closed, the neck is formed and the threads are machined. The DDI process produces the most consistence wall thickness resulting in the lightest weight, most efficient cylinders. This manufacturing process is what allows us to supply cylinders with the best buoyancy characteristics for scuba diving . Other suppliers are selling cylinders that are manufactured using the Billet Piercing or 'Spun' Tube process. These cylinders are generally heavier with less preferred buoyancy characteristics than those manufactured using DDI.

No Exterior Rusting...We Guarantee it for the lifetime of the cylinder!
During the process of Hot Dip Galvanizing, the exterior of our steel cylinders are submerged into 840ºF molten zinc. The process deposits an 8-10 mil thick zinc barrier to protect against the corrosive ocean environment. This layer of zinc metallurgically bonds to the steel cylinder. It will not chip and wear away like a painted zinc finish. XS Scuba is so confident that exterior rust will not be an issue, we guarantee it for the life of the cylinder. If the exterior of your XS Scuba HDG steel cylinder rusts, we'll correct it for as long as you own the cylinder, without cost to you.
