Dive Gear Express offers diving products labeled Nitrox Ready, whose oxygen-compatible components are free of hydrocarbons and other contaminants. All cylinders from Dive Gear Express are special order cleaned for oxygen service at the factory and sealed with an oxygen-compatible cap before shipment to us. We install an oxygen clean and oxygen compatible valve. With Dive Gear Express, you don't have to make
expensive aftermarket alterations to use oxygen-rich gas mixtures.

Available Aluminum Cylinder Finishes
"Clear Brushed" "Brushed No-Coat" "Shot-Blast"
Experienced divers prefer unpainted aluminum cylinders because unpainted cylinders better resist corrosion and
retain their appearance with heavy use. We offer the brushed no-coat factory finish on our aluminum cylinders.
"Clear Brushed" is a shiny clear coating with poor durability and is often confused with unpainted
finishes.
"Brushed No-Coat" is a smooth bright unpainted finish that retains it's appearance with heavy use.
"Shot-Blast" is a textured matte unpainted finish, decals do not adhere well to shot-blast.
Tek Tip
The Price of the Standard Aluminum 80 SCUBA Tank
Consumers sometimes use the price of an standard aluminum 80 (AL80) as a benchmark to evaluate the prices of a SCUBA equipment retailer. Many retailers price the standard AL80 at near cost, and then include free air fills to further discount the price to below their actual cost. The retailer thus sells the AL80 at a loss
in order to appear to have good prices overall. If you are shopping for an air-only standard AL80 with a K-valve, you will probably find an excellent price at your local dive shop. However, an increasing number of
retailers no longer stock aluminum cylinders because they are not profitable.
Look carefully at what Dive Gear Express includes in our cylinder prices. Both the cylinder and valve
are Nitrox-Ready and say so on our VIP sticker. We install the valve with a Viton neck O-ring and oxygen-compatible
lubricant; no VIP re-inspection fee is necessary before filling. Our price includes the better-quality Thermo Pro
DIN/K 200 bar valve with insert, protector cap, and spare Viton O-ring for valve face. Our price also includes FREE
shipping, without any additional surcharges. We can prepare your cylinder with stage straps and MOD markings or
assemble them into doubles packages.
Cylinders may ship from a different location than the balance of your order and may not arrive in a single delivery.
Cylinder prices do include FREE continental U.S. domestic shipping.
Cylinder prices do NOT include international shipping.
