Rating: Great Set of Doubles
Reviewer: Matthew G.  -  View all my reviews
I ordered the 85cu 300 bar din tanks. They were shipped in 3 boxes and arrived quickly. The valves are very smooth to operate. I removed the tank boots, and the tank heights match up nicely. They are a great set of doubles that trim out very well.

    Hi Howard, The total weight for this system is 120lbs.

  • Kristy:

    What is the weight on the 85s?

    Bill  (Certified Scuba Instructor at Scuba.com):

    Each tank is 34.3 lbs. empty weight.

  • James:

    I would like to purchase the set of Low pressure Twin 95s you sell Worthington and Highland millwork bands. I have LOLA valves for the tanks but I need to have an inter valve connector made for the 8" tanks. Please let me know. What is the distance between the center of the tanks when mounted in the Highland millwork bands? If you would, Also give me the distance for the HP steel tanks mounted distance. Can I purchase just the tanks, boots and bands without the valves and isolators? Thank you for your assistance! I look forward to buying the tanks. Very Best Regards James E.

    Actually Worthington went out of business and their tanks are no longer available. The double set up would be using faber tanks.

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!

More volume in a compact cylinder
Includes XS Scuba DIN/Yoke convertible valve and durable, self-draining boot
Inlet thread is standard 3/4'-14 NPSM
Ultimate weight to capacity ratios
Ideal buoyancy characteristics
Manufactured to DOT Exemption and Canadian TC Permit

Low Pressure - 2400+ psi service pressure
Six different models, Three different diameters

Hot dip galvanized exterior finish
Chromium Molybdenum (4130) steel alloy construction
'Plus' rated for 10% overfill to 2640 psi
Compressor-friendly, lower pressure
Includes XS Scuba DIN/Yoke convertible valve and durable, self-draining boot
Inlet thread is standard 3/4'-14 NPSM
Traditional, proven design
Negatively buoyant throughout the dive
Manufactured to DOT 3AA standard
Meets Canadian TC3AAM specifications

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
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
Included with all XS Scuba steel cylinders
Quality, self-draining design


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.
