VEVOR CO2 Tank, 5 lbs New Aluminum Alloy Cylinder, CGA320 Valve, DOT Approved Review (2026)

Who this tank is for

This is a new 5 lb aluminum CO2 cylinder built for draft beer dispensing, soda making and other pressurized beverage setups, which makes it a natural fit for a homebrewer converting a spare refrigerator into a kegerator or adding a second gas source for a growing keg collection. Choosing a new cylinder rather than a swapped exchange tank means the buyer knows the exact age and history of the tank from day one, which matters to brewers who want a fresh hydro test date rather than an unknown swapped cylinder from a beverage distributor. At 5 lb capacity it suits a one or two keg home setup better than a large multi keg draft system, where a bigger 10 or 20 lb tank would mean fewer refill trips.

Construction and valve details

The cylinder is made from aluminum alloy, which keeps it noticeably lighter to carry and move than an older style steel tank of the same capacity, and the aluminum body also resists rust in the way bare steel does not, which matters in a damp kegerator or garage setup. A gray powder coated finish adds a layer of protection against scuffs and corrosion during regular handling. The tank uses a standard CGA320 valve, which is the connection size used by virtually all CO2 regulators sold for homebrewing and draft beer, so it will thread onto an existing regulator without an adapter, and it carries dual DOT and TC certification marks confirming it meets transport and pressure vessel standards in both the United States and Canada.

What to expect out of the box

Like essentially every CO2 cylinder sold new, this tank ships empty rather than pressurized, so a first stop at a welding supply shop, homebrew shop, or beverage distributor that fills or exchanges CO2 tanks is required before it can carbonate or serve anything. A 5 lb charge of CO2 is generally enough to carbonate and dispense through roughly six to eight typical homebrew kegs before a refill is needed, though actual mileage depends on serving pressure, line length and how often the system is left connected and slowly leaking through fittings. Because this is a new tank rather than a swap, some local fill stations may want to inspect or test it before their first fill, so it is worth calling ahead.

New tank versus exchange programs

Many gas suppliers run a swap program where an empty tank is exchanged on the spot for a full one, which is faster than waiting for a fill but means the tank a brewer eventually owns may not be the same one purchased, and can even be an older or more worn cylinder than the new one bought here. Buying a new aluminum tank like this one avoids that uncertainty at the cost of the initial purchase price, and aluminum tanks generally hold their resale value and cosmetic condition better than steel over years of use. Competing 5 lb aluminum tanks from other brands offer similar specifications and DOT approval, so the choice between them often comes down to coating color, price and what a given seller has in stock.

Bottom line for kegerator setups

For a homebrewer building out a kegerator or adding gas capacity, this 5 lb aluminum tank delivers a lightweight, corrosion resistant cylinder with the standard CGA320 valve and dual DOT and TC certification, matching our score of 8.6 out of 10 for fit and value. The trade offs are that it arrives empty and needs a local fill before first use, and that some exchange programs will swap rather than return this exact tank over time. Brewers who serve from more than two kegs regularly, or who go through gas quickly, should consider a larger 10 or 20 lb tank instead to cut down on refill trips.
