Questions and Answers for XS Scuba X Series High Pressure Twin Cylinder / Tank Package - 300 DIN Valve:

  • David:

    what changes have to be made to bcd to accomodate twin tanks?

    Clarke  (Certified Scuba Instructor at Scuba.com):

    Hello David, Thank you for your inquiry! The XS Scuba X Series High Pressure Twin Scuba Cylinder Package - 300 DIN Valve is a complete package. You’ll only need to make sure your BCD is set up to handle doubles. Most BCD HARD backpacks have indentations as to where to drill out the holes for the 2 bolts, allowing the twin tank bands to be secured to the BCD. If you have a soft back BCD, most manufactures have steel, stainless steel or aluminum back plates that can be integrated into the BCD. http://www.scuba.com/scuba-gear-89/043223/XS-Scuba-X-Series-High-Pressure-Twin-Scuba-Cylinder-Package---300-DIN-Valve.html If you would like to place an order or have questions about our products, please contact one of our certified Dive Instructors at SCUBA.com by calling 800-247-2822 <> 949-221-9300 or e-mail us at: info@scuba.com

  • Larry:

    How much less weight is the double 80 package that a double 100 package?thanks

    Bill  (Certified Scuba Instructor at Scuba.com):

    The 100s will be about 6 lbs more on the empty weight than the 80s.

  • Ace:

    what is the weight of the twin 80 cft tanks.

    Darrick  (Certified Scuba Instructor at Scuba.com):

    Hello Ace, to get the total weight of this item you would need to contact the manufacture directly. You can call them at 866.977.2822.

    Bill  (Certified Scuba Instructor at Scuba.com):

    Twin 80's empty weight is around 65lbs.

  • ace:

    what about 45 or 60 cft. twin tanks.can I find a manifold. i know a few years back i had twin 72cft. steels and they were great. it seems hard to find twins any more.

    Bill  (Certified Scuba Instructor at Scuba.com):

    Twin 80s will be the closest to the 72s and are easier to find manifolds and bands.

  • brad:

    The information states that the XS steel tanks are NITROX ready. How about the 300 DIN manifold: it it 40% NITROX ready or will it have to be converted and cleaned?

    Darrick  (Certified Scuba Instructor at Scuba.com):

    Hello Brad, when you order that package everything will be Nitrox ready.

  • Nick:

    How long will the 80 twin tanks last when their full

    Arthur  (Certified Scuba Instructor at Scuba.com):

    Hello, this is a lot of air! Air consumption depends on depth and exertion. Just to give you a number at 30'' you could get up to 2hours with minimal exertion.

  • Phillip:

    Are these still actually available with Worthington Cylinders as indicated? Inches in Diameter: 7.25" for X7 Series Manufactured by Worthington Cylinders COLOR: Hot dipped galvanized

    Arthur  (Certified Scuba Instructor at Scuba.com):

    Hello, Worthington tanks are long gone. They have been replaced with faber tanks.

  • Alex:

    how many cubic feet of air XS Scuba X Series High Pressure Twin Cylinder / Tank Package - 300 DIN Valve holds and how much time under water would that be?

    Darrick  (Certified Scuba Instructor at Scuba.com):

    Hello Alex, it cubic feet of the tank would depend on what size tank you get. This comes in wither a 80cf or 100cf size. As for how long it will last you depends on your breathing rate. Each person breaths differently underwater.

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.
