Rating: X7 LP108 tanks
Reviewer: Thomas P.
The tanks arrived a day ealier than what shipping indicated. It was perfect timing to take them for a dip. I have been diving shop LP108s for years and really love the trim and balance of these tanks. These new ones seem a little heavier than the ones i have dove before and i need to fine tune my rig for these, but its nice that i can take "my" tanks with me on any dive now and know exactly how they have been treated and used. No longer do i have to guess as to the state of shop tanks. Anyone looking for great tanks needs to look at LP 108s. You need to remember that the labeled working pressuer of 2400 is only because the X7 rating is more conservative than the X8 high pressure tanks. When filled to a proper working pressure of 3500 PSI this tank holds 140cft of gas. Remember that the hydro pressure for this tank is 4500psi and i have never heard of a low pressuer tank failling due to over pressuer. By design the 300bar valvle will fail before the tanks does. I also love the valves one these tanks the visual indicator leave no doubt as to wether your gas is on or off and the convertable capabilities lets me switch from yoke to Din depending on the dive enviornment. I can say enough good thing about these tanks.

Rating: Very Very Satisfied
Reviewer: Ronald Turpin
These tanks are absolutely awesome. They hold a ton of air and I love the neg buoyancy. Was able to take out 5 lbs of weight from my BCD. I took my 2 108s out the other day and made four dives off of them. Scuba.com was a pleasure to work with. Very good communication and super service.

Rating: Great tank
Reviewer: Arthur Woolard
Get a hard fill and you will have 130 cf of air. Great for spear fishing were you need lots of air.

Questions and Answers for XS Scuba 108 Cubic Foot Low Pressure Steel Tank:

  • Jim:

    Ok I want a lp Steel tank. But I see that the PSI is way less then Al tanks. So do I loss a lot of dive time? Not sure I under stand these numbers?

    Bob  (Certified Scuba Instructor at Scuba.com):

    It is the cubic foot measurement of a cylinder that will always dictact the amount of air it can hold. The pressure rating is simply the amount of pressure it takes to get a full fill. For example the tank you are looking at here would have 108 cubic feet of air in at at 2400psi. And alumimum 80 has less air regardless of it's pressure as when it's full it still only holds 80 cubic feet of air.

  • jeff:

    Is there an advantage that an lp tank has verus and hp? thanks

    Greg  (Certified Scuba Instructor at Scuba.com):

    LP tanks can be filled from just about every dive shop or dive boat in the world.

  • Chris:

    Is this tank really a galvanized finish or is it a painted faber?

    Darrick  (Certified Scuba Instructor at Scuba.com):

    Hello Chris, no this is a galvanized dipped tank.

  • J:

    What is the born date on the 108 or 95 xs lp tank??

    Darrick  (Certified Scuba Instructor at Scuba.com):

    Hello J, you are looking at 3-4 month date on the tank from when you place your order.

  • Bill:

    What is the diameter of a worthing LP 85cf tank with a standard tank boot.

    Arthur  (Certified Scuba Instructor at Scuba.com):

    Hello, the diameter would be 8.75"

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
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!
