best tank made
not all tanks are made the same. the hot dipped galvanized tanks by worthington are by far the best tanks for the money. unlike other steel tanks that when the protective coating chips off the tank starts to rust and pit these tanks do not. steel tanks keep their negative buoyancy unlike aluminum tanks that float after you burn thru your gas. this lets you dive with less weight.
i have me own air compressor so i like the low pressure tanksit is easier on the compressor unit unlike high pressure tanks that beat up a compressor pretty bad.
the xs valve is very tough and when the tank is open it shows a green ring around the valve handlered when the air is shut off- my wife likes the visual check just to make sure.

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!
X-Series™ High Pressure - 3442 psi service pressure Six different models, Two different diameters X7 - 7.25' diameter X8 - 8.00' diameter Hot dip galvanized exterior finish Chromium Molybdenum Vanadium steel alloy construction High-strength steel technology 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
LP-Series™ 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 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
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.
