ICO Threaded 16g Cartridges — 10 Pack
Best for: Home brewers and mobile setups using threaded systems. These 16-gram cartridges are designed for high-pressure performance, delivering quick and reliable carbonation for standard road tires and beverage dispensers alike. The 3/8″-24 TPI threading ensures compatibility with common CO2 inflators and beverage gear, while the 11mm neck length supports a tight seal for minimizing leaks. The cartridges are certified food-grade and EU-standard safe, making them suitable for pressurized mini-kegs and soda makers without metallic aftertaste.
Why selected: This option balances portability with reliable, sealed carbonation for beverage devices that use threaded chargers. It’s a practical choice for frequent pours and compact setups. Caution: Confirm your device accepts 3/8″-24 TPI threads to avoid mismatches.
ICO Non-Threaded 16g Cartridges — 10pcs
Best for: Portable beverage dispensing without a tank or regulator. These unthreaded cartridges are designed for universal use with beer machines, CO2 growlers, and other devices that require 16g cartridges. They are made of recyclable steel and provide about 60 bar / 900 psi, offering a clean CO2 source without mineral content that could affect taste.
Why selected: Ideal when you need ease of transport and broad compatibility across multiple devices. Limitation: Not suitable for systems that require threaded connections.
Cooler Keg 74g CO2 Cartridges — 4 Pack
Best for: Portable beer systems and small kegs that require longer-lasting gas. Each cartridge provides substantial CO2 for powering two kegs from full to empty, with some left for cleaning. The cartridge size is 74 grams, designed to fit commonly used 5/8″-18 UNF threading on Cooler Keg devices. It’s eco-friendly since empty cartridges are recyclable.
Why selected: Great for events or frequent dispensing where cartridge turnover matters. Caution: Check compatibility with your specific keg model’s threading (5/8″-18 UNF is common but not universal).
ICO 16g Cartridges (30 Pack)
Best for: High-volume dispensing and frequent beer serving. This 30-pack provides a steady supply for systems that rely on 16-gram threaded cartridges. The design mirrors the standard 3/8″-24 TPI thread and an 11mm neck length, ensuring reliable seals and compatibility with beverage devices that require threaded chargers.

Why selected: High-capacity option that reduces cartridge swaps during long sessions. Caution: Not compatible with SodaStream or non-threaded CO2 systems.
Buying Guide: Key Considerations For CO2 Cartridges For Beer Keg
- Thread compatibility: Threaded (3/8″-24 TPI) versus unthreaded designs determine which devices you can power. Choose threaded for many kegerators and regulators; unthreaded for universal, non-threaded dispensers.
- Cartridge capacity: 16g cartridges are common for portable pours; 74g cartridges power larger setups longer. Match capacity to your number of kegs and expected pour volume.
- Food-grade safety: Opt for cartridges labeled beverage-grade or food-grade to avoid metallic or off-flavor contamination in beer and other drinks.
- Device compatibility: Verify threading, neck length, and whether your equipment expects a fixed regulator or accepts quick-change cartridges.
- Portability vs. economy: Smaller packs offer portability; larger packs reduce replacement frequency but require more storage and rotation.
- Disposal and recycling: Many cartridges are recyclable; check local recycling guidelines to minimize waste after use.
