Tek Tip Warning Image WARNING
According to our suppliers, their Nitrox Ready and Oxygen Service products are compatible with oxygen and factory cleaned for use with compressed gases in excess of 23.5% oxygen. Nonetheless, the 'clean state' of this equipment applies only prior to initial use. Thereafter, periodic inspection and cleaning are a necessity. You must meticulously follow the recommendations of the US Department of Transportation (DOT), Compressed Gas Association (CGA), and other federal/state/local agencies, plus your dive training agency for equipment maintenance, handling, storage, labeling, filling, transport and use of compressed gases. Oxygen-related fires and explosions can result in serious injury or death. Ultimately, you must make the final decision to assume all risks associated with the use of any compressed gases, including those in excess of 23.5% oxygen.

SCUBA Tanks must be hydrostatically tested every five years (60 months). The larger primary cylinders typically have a factory hydro date between 3 and 9 months old, but not more than 12 months old. Smaller cylinders may have a factory hydro date up to 24 months old as these are manufactured less frequently.

Our cylinders and valves are Imperial 3/4 NPS neck threads, NOT Metric M25 neck threads, and the valves have overpressure relief devices. The cylinders have US DOT and Canadian CTC markings suitable for use ONLY in North America. Our cylinders and valves are NOT CE approved and NOT suitable for use in the European Union. Cylinders are NOT marked appropriately for use in Australia and New Zealand.
