Stainless Steel CO2 Check Valve

Description

Stainless Steel CO₂ Check Valve

This compact stainless steel CO₂ check valve is designed to prevent backflow in pressurized aquarium CO₂ systems, protecting regulators, solenoids, and other upstream equipment from moisture intrusion. The internal spring-loaded mechanism allows reliable one-way flow under CO₂ pressure while maintaining a secure seal when pressure drops.

This valve is intended specifically for pressurized CO₂ applications and is not suitable for low-pressure air pump systems.

Important Note
Not recommended for air pump use. The internal spring pressure may be too strong for standard air pumps and air stones.
