The Wyin Aqua Quick-Plug CO₂ Check Valve is the perfect safeguard for your aquarium CO₂ system. Designed specifically for standard 4/6mm aquarium tubing, it prevents water from flowing back into your regulator, diffuser, or bubble counter – protecting your gear from costly damage.
Key Features:
- Fits Standard Tubing – Compatible with all standard 4/6mm (4mm inner diameter, 6mm outer diameter) CO₂ and aquarium airline tubing.
- One-Way Flow Protection – Prevents backflow into sensitive CO₂ equipment.
- Quick-Plug Connector – Push-to-connect design for easy installation and a secure, leak-free fit.
- Durable Aluminum Alloy Body – Built to resist corrosion and last.
- Reliable Performance – Minimum working pressure: 0.3 bar (4.3 psi). Ideal for pressurised CO₂ systems (not suitable for low-pressure air pumps).
Specifications:
- Material: Aluminum alloy body with quick-plug fittings
- Length: 46mm
- Hose Size: Fits 4/6mm standard aquarium tubing
- Minimum Operating Pressure: 0.3 bar / 4.3 psi
- Directional Flow: Marked with arrow for correct installation
Installation Instructions:
- Locate the arrow on the valve – it shows the direction of CO₂ flow.
- Push your 4/6mm CO₂ tubing firmly into both ends of the quick-plug fittings.
- Run CO₂ at low pressure first to test for leaks.
- Position upright with arrow pointing towards your diffuser or reactor.
Tip for Fishkeepers: Always double-check connections before turning your system fully on. This valve is designed for pressurised CO₂ systems, not small air pumps.
