Get yourself a long-lasting, quality cylinder with this Catalina Aluminum Scuba Cylinder. Unlike steel cylinders, aluminum tanks resist rusting. Instead, they oxidize which forms a protective coat that reduces the potential for corrosion. Every Catalina Scuba Tank is nitrox ready, and each one has a serial number that can be traced to its production batch for information on test reports and even the raw materials used to make it. The cylinders go through a fascinating process to be made and are quality checked every step of the way
