Review on 🐠 Pawfly 40-Piece White Plastic Inline Tubing Aquarium Air Valve Connector, 3-Way T and Straight by Lisa Stubbs

These connectors worked as advertised but there were signs that the manufacturing process was poor. The plastic has not been trimmed cleanly at the ends and often you will find a piece of plastic left over. It's easy to remove with a razor blade, but I thought it might be internal ones that would restrict airflow. I am happy to report that this is not the case. In every application I've used them in, they've worked as they should.
