Review on 💪 Powerful & Reliable: Kleinn Air Horns 307 Vortex 4 12-Volt Air Horn Solenoid Valve by Alex Gilbert

I think all the bad reviews about this solenoid is because it was installed incorrectly. Most of the descriptions in these reviews describe exactly what kleinn says in his installation video if you don't get the lines in the right order. The line coming from the side of the solenoid goes to your air tank and the line coming from the end of the solenoid goes to your horn or whatever you use it for. Hanging them back can cause loss of pressure and inevitable failure as the solenoid uses directional airflow. The wires don't matter which ones are connected, they are not polarized. The reason I gave it 4/5 stars is because it has 1/8 page adjustment. It's very hard to find a 1/8 NPT fitting that actually screws in. It's as if the threads were custom made for the compression fitting included in the kit, which I didn't use because I wanted it to connect directly to my tank with no line. Eventually I stumbled across a fitting where I could grab a few threads to get started, but I almost gave up. The tolerances were too tight.
