CO2 Accessories & Gear
Common “starter kit” items people end up needing for CO2 setups. You don’t need everything. Pick what fits your use-case and stop buying random parts out of panic.
Quick picks
The stuff that solves the most common problems: tipping, leaks, incompatible connections, and regret.
Tank strap / mount
Prevents tipping. Cheap safety upgrade, especially at 20 lb and up.
CO2 regulator
Match your use-case (keg vs aquarium is not the same vibe).
Adapters
Only if you’re connecting to small-bottle systems (SodaStream, paintball, etc.).
Gear by use-case
Lightweight for now. This is a routing layer, not a shopping empire.
Homebrew / kegerator
- Primary regulator
- Spare washer/O-ring kit (tiny parts, huge annoyance)
- Tank strap/mount
Aquarium (planted tank CO2)
- Aquarium-style regulator / needle valve setup
- Bubble counter / check valve (depends on your build)
- Secure cylinder placement
Soda / carbonated water
- Adapter compatible with your system
- Regulator if your setup needs it
- Leak-check basics (so you don’t slowly vent money)
Paintball
- Thread/valve compatibility varies by tank
- Fill policies vary wildly by shop
- Swap programs can be easier than refills in some areas
