CO2 High pressure check valve >100psi resistance. With the incredibly low opening pressure of 1 psi (0.0068 Bar)!
Water can be siphoned from the aquarium into the CO2 hose. If a check valve is not used, water could enter the solenoid valve and CO2 pressure regulator. There, this water can cause instability, resulting in damage to equipment. By using a CO2 check valve, the CO2 system is protected against the backflow of water.
This check valve has simple push-in connections for easy installation in combination with CO2 pressure hose. Compatible with any CO2Art CO2 Resistant Tubing.
