Aquarium Check Valve

Product Code: ACV1C
MPN: A1165

The Marina® Aquarium Check Valve is a compact, one-way inline air valve designed to prevent aquarium water from siphoning backward through airline tubing into an air pump. Installed between the air pump and the aquarium, it provides reliable protection against backflow during power outages or when the air pump is turned off, helping to prevent pump damage and accidental flooding. Its low-resistance design maintains efficient airflow while providing dependable, leak-resistant operation. This high-quality Aquarium check valve can be used with 3/16" or 5/32" I.D. tubing. Resistance at .07 cfm is only 3" H2O.
