Overview
The Stainless Steel COâ‚‚ Check Valve is an essential safety component for pressurized COâ‚‚ systems. Made from corrosion-resistant stainless steel, it ensures one-way flow and protects your regulator, solenoid, and diffuser from water back-siphoning during power outages or system shutdowns.
Key Features
- Corrosion-resistant stainless steel: Durable and long-lasting compared to plastic alternatives .
- One-way valve design: Prevents aquarium water from flowing back into your COâ‚‚ equipment when pressure drops .
- Standard 4 mm ID / 6 mm OD compatibility: Fits most CO₂ lines for easy integration .
- High-pressure rated: Designed for pressurized systems—air pumps are not suitable .
- Compact & easy to install: Inline unit with flow-direction arrow; install near the tank rim .

Why Choose Stainless Steel?
- Superior durability: Outlasts plastic versions under constant pressure and humidity .
- Protects equipment: Stops water from damaging delicate components like regulators and bubble counters .
- Maintains pressure: Holds 20–30 psi in the line even when CO₂ is off, preventing delays on restart .
- Simple installation: Direction arrow ensures correct placement; fits standard tubing effortlessly .
Usage & Maintenance
- Cut your COâ‚‚ line outside the tank rim.
- Insert valve inline with arrow pointing toward the aquarium .
- Secure the tubing and run COâ‚‚ as usual.
- Check periodically—stainless steel won’t degrade, but spring mechanism may benefit from occasional checks.
