Frequently Asked Questions
Q: What gases can be used with this high pressure aluminum cylinder?
A: This cylinder is designed for legal gas applications including CO2 (for aquarium plant systems and soda carbonation), compressed air, and diving-grade oxygen or air mixtures. Always ensure the gas type is compatible with aluminum alloy cylinders and follow local regulations for gas handling.
Q: What thread size does this gas cylinder use?
A: The cylinder features an M18×1.5 thread specification, which is a standard thread size compatible with many regulators, valves, and fittings designed for high pressure gas systems. Always verify compatibility with your regulator before use.
Q: Is this cylinder certified for safe use?
A: Yes. This cylinder is manufactured to GB11640-2011 standards and carries TS Certification. It is constructed via aluminum alloy high pressure integral molding with a 6.3mm wall thickness and a rated working pressure of 30 MPa / 4500 PSI, with an ultimate burst pressure of 86.2 MPa for a wide safety margin.
Q: What capacity options are available?
A: This cylinder is available in four capacity options: 0.25L, 0.35L, 0.45L, and 0.5L. Choose the size that best matches your application — smaller volumes are ideal for portable use, while larger capacities provide extended supply time for aquariums or carbonation systems.
