Overview
The DIY CO₂ Glass Diffuser with Check Valve & U-Pipe is an all-in-one solution for homebrew CO₂ injection. It combines a clear glass bubble counter and diffuser, integrated one-way check valve to prevent backflow, and a U-pipe hook for tidy, rim-mounted installation.
Key Features

- Built-in check valve: Prevents water siphoning back into the CO₂ system—essential for protecting DIY reactors & regulators .
- U-pipe glass hook: Smooth rim transition avoids kinks in CO₂ tubing and keeps tubing discreet .
- Glass construction: Clear, elegant glass chamber enhances aesthetics and allows easy visual checks.
- Suction cup mount: Keeps unit stable; easy to remove for refilling or cleaning.
