Aquarium Airflow Control Kit

I recently bought an Air Control kit, but use the valves more for water drip control. They work great for slowly adding water to my tanks or for drip acclimating.
Thank you Flip Aquatics’s!! Y’all are the best.

This had everything I needed, except for a straight in-line coupler, which I need to periodically detach one of my air lines. However, I knew that before I bought it, and it doesn't detract from the fact that it delivered as promised.
