Rating: Steel tanks are a must have
Reviewer: Ryan Rexroad  -  View all my reviews
A steel dive tank is a must have if you are an avid diver. Superior buoyancy, drip weight, the weight is distributed evenly, never any positive buoyancy as an aluminum tank. Price is a little higher than aluminum but, worth every penny. I would never dive with an aluminum tank again. Oh and the more cubic ft of air, more bottom time.

Rating: 100 cubic high pressure tank
Reviewer: Craig C.  -  View all my reviews
Finally able to try the 100 cubic high pressure tank last night with my other new equipment. I purchase a Black Ice BC and was not sure how much weight I may need so I started off with 4 lbs. on either side of my quick release pockets. I was amassed that I did not need the 8 lbs. Great tank and would recommend!

Rating: Really Pleased
Reviewer: Michael Albert
Of course, other reviews have already mentioned the excellent quality of the tanks and the advantages of steel over aluminum. Naturally, the higher capacity versus 80cu foot tanks is also a plus. I also very pleased with the valves. Theyre very good quality, and switching between yoke and DIN fittings just takes an allen wrench and less then 10 seconds.

Rating: Steel, the only way to go
Reviewer: George W C.  -  View all my reviews
For me, diving with a steel tank is the only way to go, unless someone gives me a CCR kit. My steel tank is very compact, I love everything about it.

Rating: Great Tanks
Reviewer: chris wimmers
I bought two of these tanks and love them. This site is great. You cant find dive equipment any cheaper anywhere especially when there is free shipping. I dont need to explain all the good benefits from using steel 100cu feet tanks.

Reviewer: Yvonne Kitchen  -  View all my reviews
I ordered this item on line. I am not that informed about the product as I ordered it for my husband for christmas. I called the contact number and was given a very helpful saleperson who in turn knew just what I was looking for. He was right my husband is thrilled with the tank and I owe it all to the advise of a well informed salesperson and the easy web site.

  • enhydra:

    Your site says the cylinder length is 24", however, XS Scubas (the Worthington distributor) specs cite the tank being 22.7" (http://www.xsscuba.com/tank_steel_specs.html). Which is correct length for the tanks you have in stock?

    Darrick  (Certified Scuba Instructor at Scuba.com):

    Hello Enhydra, they measure without the valve installed. The 24" is with the valve in installed.

  • Gary:

    Hello, On the 100CU steel tank Xs100, does this come certified to go right to Nitrox? Also, does it ship for 100% free or are there ancillary charges for shipping? Secondly, can I use my standard regulator with this tank? If so, I assume I do not have to convert to DIN. Can you tell me the circumference of the tank, the height with valve and the weight empty?

    Clarke  (Certified Scuba Instructor at Scuba.com):

    Hello Gary, Thank you for your inquiry! Yes, the XS Scuba 100 Cubic Foot High Pressure Steel Scuba Tank is Nitrox Ready, up to 40% (the recreational limits of nitrox). And the cylinder is eligible for Free Standard Ground Shipping. http://www.scuba.com/scuba-gear-131/043254/XS-Scuba-100-Cubic-Foot-High-Pressure-Steel-Tank.html It’s a High Pressure tank that is compatible with any regulator by utilizing the Pro Valve-Standard Yoke and DIN Compatible http://www.scuba.com/scuba-gear-225/042067/XS-Scuba-International-Valve.html • Inches in Diameter: 7.25" • Inches in Length: 24" • Weight Empty = 33lbs • Buoyancy Full = -10lbs • Buoyancy Empty = -2.5lbs When ordering, be sure to add a Valve protector and a tank carrier.

  • Agung:

    Hi, some questions: 1. Is it ASME U-stamp? 2. Can I order directly from Indonesia? (about 12pcs) 3. Could you inform me what email address and the person I can contact later? Thank you.

    Bill  (Certified Scuba Instructor at Scuba.com):

    Email to gsa@scuba.com for more information and a quote.

  • Daniel:

    I just ordered these exact same tanks from my LDS, they informed me that these tanks do not come o2clean and that if I wanted to run Nitrox up to 40% I would have to spend the extra $150 with them to have them cleaned, so I did. However if your tanks are Nitrox ready upto 40% than why do they not come with the VI sticker stamped or the Nitrox sticker. This is very frustrating because I would like to know who I can trust spending my money with in the future.

    Darrick  (Certified Scuba Instructor at Scuba.com):

    Hello Daniel, the reason we do not put nitrox stickers on the tanks is not everyone dives on mixed gas. Plus we do not have Nitrox at our retail store. If you have any other questions or would like to place an order please feel free to give us a call at 1.800.347.2822.

  • Tom:

    What is the life span of an aluminum tank (80). I have a few tanks from the late 80s and early 90s. Hydro tested as required but how long can this go on?

    Bob  (Certified Scuba Instructor at Scuba.com):

    There is no set lifespan for a tank. They are designated by DOT to be hydrostatically tested every 5 years and so long as they continue to pass this test, could feasibly remain in service for decades.

  • Mike:

    What size are the tank/valve neck threads?

    Bill  (Certified Scuba Instructor at Scuba.com):

    All the cylinders will be a standard 3/4 - 18 size thread, except for cylinders rated at 3500 psi or greater.

  • Kevin:

    what is the water volume of a 88 CF, 100CF Hp (3442 PSI/237 BAR) stell scuba tank, please

    Bob  (Certified Scuba Instructor at Scuba.com):

    SCUBA cylinders sold in North America are typically rated according to their surface equivalent air volume. For example, a steel 80 contains approximately 80 cubic feet of gas at ambient pressure, compressed down to the volume of the cylinder, which is only a couple of cubic feet. Conversely, cylinders sold in Europe are most commonly rated according to their actual volume (water capacity) - so the European equivalent of the 80 cu.ft. at that approximate psi here would be a 10 L cylinder. The 100CF steel tank would be approximately 12 liters. And again, these volumes are approximate.

  • Wallace:

    Is the standard/included black tank boot octagonal or round (I want octagonal to increase rolling resistance)?

    Darrick  (Certified Scuba Instructor at Scuba.com):

    Hello Wallace, yes it comes with that style boot when you buy the tank.

  • wayde:

    For a beginner is this the ideal tank, or should I go with aluminum.

    Bill  (Certified Scuba Instructor at Scuba.com):

    Aluminum will be cheaper, but the buoyancy of the tanks when they get empty is the biggest difference. Steel will stay negative throughout the dive.

  • Brian:

    What is the free visual inspection program that is included with these tanks?

    Bob  (Certified Scuba Instructor at Scuba.com):

    The tank will come with it''s first VIP having been already performed and stickered.

  • Ronn:

    Is the Pro Valve included with the HP100 tank the VX200 with the Safety Handle?

    Darrick  (Certified Scuba Instructor at Scuba.com):

    Hello Ronn, yes this tank comes with the valve with the color coating to let you know if the tank is open or close.

  • Ray:

    Do you have these in stock ready to ship?

    Bob  (Certified Scuba Instructor at Scuba.com):

    As this is an ongoing product knowledge database available inventory can change from one reading to the next. For information on stock status or inventory levels please contact our instructors at info@scuba.com

  • William:

    Hi - I thought Worthington shut down their plant this past January and all steel 100s were sold - never to return? Do you actually have these in stock and they are the actual Worthington X7 Steel 100 tanks? Just checking!

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!

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.

XS Scuba High Pressure Steel Tanks

A scuba cylinder is a tough thing to write a review on. After all, a tank is a tank. With a little research we find that aluminum tanks float at the end of a dive, are made of softer material, but are the most inexpensive tank to purchase. Hence their popularity in shops, diver’s garages and rental inventories.

We also can learn that steel cylinders are expensive but usually that’s about as far as we get. The price sells. XS Scuba has made great strides in combating this. While their steel tanks are still more expensive than the aluminum version, they are not so far apart in price as they used to be. In fact, they are priced in a way that makes it difficult to justify purchasing a cylinder that doesn’t offer what they do. The very first thing that catches your eye is the over all size of the tank. The Steel 80 cubic foot tank is only 19.7” tall! That is smaller than a standard aluminum 63 cubic foot tank! It is negatively buoyant when full, of course but it’s also negative when it’s empty. What that means for you is lead taken off of your weight belt or out of your pockets that the diver used to need to compensate for the aluminum tank. Less lead = more comfort.

The 100 cubic foot tank is only 24” in length, and is smaller than the aluminum 80 it is compared to. These smaller tanks, offering the same if not more air once again equates directly into comfort for the diver. No longer is it necessary to lug around something resembling a hot water heater or a torpedo to get the maximum amount of bottom time out of your tank.

The next cool feature is that both tanks have a fill pressure of less than 3500psi. 3442 to be exact. That means there is no need for you to purchase a DIN first stage any longer! No worry about having a DIN to Yoke adapter so you can take your gear on vacation and no more getting stuck with a more expensive regulator simply because you wanted a smaller tank.

All in all, with great pricing and a list of advantages over the old aluminum tank, there is no reason at all that every diver shouldn’t be diving with an XS Scuba High Pressure Steel Tank!
