Hagen Marina Plastic Non-Return Check Valve

(Code: GK-HGA1165)
For accurate, leak proof aquarium aeration, the Marina Non Return Plastic Check Valve is an essential component.

Preventing water from siphoning out through airline tubing from the aquarium in the event of a power failure or aquarium maintenance, the check valve avoids damage to air pumps.

The valve also allows flow restrictions and controls to suit the air input to the species of fish and plants kept in your aquatic environment.
