0.5L Mini Scuba Diving Cylinder Set (2-Pack)

Compact 0.5L Diving Cylinders for Flexible Underwater Use

This set of two 0.5L mini scuba cylinders is designed as a practical addition to your underwater breathing setup. Each cylinder functions as a small-capacity gas tank intended for short, shallow dives, surface support, or as a backup air source when paired with appropriate regulators and equipment. The compact form factor allows easy packing in dive bags and convenient handling on boats or shore entries.

Constructed from robust materials suitable for underwater use, these cylinders are engineered to withstand typical recreational diving pressures when correctly filled and maintained. Their portable size makes them especially useful for activities such as underwater photography, quick inspection dives, pool training, or as an auxiliary supply during snorkeling with a compatible breathing system. Please note: these cylinders are designed to supplement, not replace, a full-size scuba tank for deeper or extended dives.

FAQ

Q: Are these cylinders a replacement for a full scuba setup?
A: No. These 0.5L cylinders are designed as accessories or backup air sources. For deeper or longer dives, a complete scuba system with standard cylinders and certified training is required.

Q: What gas can be used in these cylinders?
A: They are intended for use with breathable compressed air or appropriate breathing gas mixtures filled by a certified dive center, according to local regulations and your training.

Q: How long will one 0.5L cylinder last underwater?
A: Duration depends on depth, breathing rate, and gas pressure. These cylinders are suitable only for short, shallow use and should never be relied on as a primary air source for extended dives.

Q: Do these cylinders include regulators or a filling adapter?
A: This listing is for the cylinders only, unless otherwise specified by the seller. Compatible regulators, valves, and filling adapters must be purchased and used according to manufacturer instructions and dive training.
