2. Superior Material (AA6061): Our SCUBA tanks are crafted from premium AA6061 aluminum alloy, offering exceptional high strength, lightweight portability, and excellent corrosion resistance – ideal for underwater use.
3. Passivation Treatment: Both the interior and exterior surfaces undergo a strict passivation process. This ensures the gas remains clean, odorless, and non-corrosive, providing safety and purity for breathing air applications.
4. ISO9001 Quality Management: All production and management processes are strictly carried out under the ISO9001 Quality Management System, ensuring consistent reliability and high quality for every SCUBA tank we ship.
5. Custom & Standard Options: We offer a wide range of standard SCUBA tanks in various sizes. Additionally, we accept custom/non-standard gas cylinder orders – just tell us your specifications, and we will design and manufacture accordingly.


It depends on the size and quality. A standard aluminum tank is approximately $300 (excluding the valve).
There are two ways to attach : a Yoke adapter or a DIN connection.
Answer: With proper maintenance and without excessive use (such as daily rental use in a dive shop), a scuba tank can last 15 to 20 years.
Answer: In the USA, all tanks must undergo a visual inspection once a year and a hydrostatic inspection every 5 years.
Answer: All tanks are serviced and ready to be used with all gas mixes. However, it is the valve on the tank that determines what exact mix or blend you can safely fill into it.
Answer: Tanks are usually produced as an empty shell. However, many suppliers offer the valve as a purchase add-on so they can be delivered together and ready to use. Always verify that your regulator clamp matches the tank valve.
