VEVOR 5-Lb CO2 Tank with CGA320 Valve
VEVOR’s 5-pound aluminum CO2 tank provides a lightweight option for mobile setups and home bars. The tank features an adjustable pressure range from 0 to 60 PSI via its gas meter, helping to tune beer foaming and dispense texture. The pressure relief at 65 PSI helps maintain stability during use. It ships empty, ready to fill, and includes gaskets and clamps to reduce leaks. The aluminum construction offers rust resistance and easier handling compared with steel tanks.
Kegco 10 lb Aluminum CO2 Tank
The Kegco 10 lb CO2 tank is constructed from high-strength aluminum alloy 6061-T, offering a balance of strength and portability. It supports service pressures up to 1800 PSI (with testing up to 3000 PSI), making it suitable for larger homebrew systems and professional settings. A single fill can dispense 10-12 full-size kegs, making it an efficient choice for steady beverage output. Its rust-resistant properties help extend tank life in humid or damp environments.
GANCOWISE 5 lb Aluminum CO2 Tank
GANCOWISE’s 5-pound tank emphasizes a premium, light, corrosion-resistant aluminum build with a glossy varnish finish. It is DOT approved and ships empty. The tank’s compact dimensions (about 5.24″ in diameter and 18.27″ tall) make it practical for smaller bars, compact kegerators, or portable setups where weight matters. The CGA320 valve ensures compatibility with standard regulators, facilitating straightforward installation and maintenance.
TMCRAFT 5 lb CO2 Tank
TMCRAFT’s 5-pound CO2 tank uses aluminum alloy 6061 for reduced weight while delivering durability. It is DOT marked and shipped empty, with a CGA-320 valve pre-installed to support standard regulators. Capable of handling up to 1800 PSI service pressure and 3000 PSI test pressure, it suits kegerator kits and draft beer systems where reliable gas flow is essential. The black glossy coating offers an additional protective layer against wear and corrosion.
TMCRAFT 2.5 lb CO2 Tank
This 2.5-pound TMCRAFT tank offers a compact solution for portable dispensing needs. Built from aluminum alloy 6061, it is lighter than steel alternatives and DOT certified for safety. The CGA-320 valve is pre-installed for easy regulator compatibility, and the tank ships empty, ready for CO2 filling. Its smaller footprint makes it ideal for mobile bars, small kegerators, or occasional dispensing requirements where space is at a premium.
Buying Guide
- Capacity and usage: Choose a tank size that matches your dispensing volume. Larger tanks reduce frequent fill-ups for high-traffic setups, while smaller tanks offer portability for camping or mobile bars.
- Valve compatibility: Ensure the tank uses a standard CGA-320 valve for compatibility with common regulators and kegerator kits.
- Material and weight: Aluminum tanks are lighter and corrosion-resistant compared with steel; this matters for moving the tank and long-term durability.
- Pressure ratings: Look for a tank rated for at least 1800 PSI service pressure with a 3000 PSI test pressure to cover most dispensing needs, especially for beer and soda.
- Shipped empty: Most consumer tanks ship empty for safety; plan on purchasing CO2 gas separately and verify local filling options and re-certification schedules.
- Portability vs. stability: Consider your setup size and placement. Smaller tanks are easier to relocate, while larger tanks support continuous dispensing in busy environments.
- Maintenance and safety: Check for included gaskets, clamps, and secure valving features. Ensure proper storage away from heat sources and follow local regulations for gas cylinders.
- Regulatory compliance: DOT approval indicates compliance with U.S. gas cylinder standards. Verify tare weight markings and inspection dates when evaluating used or refurbished options.
