Review on 🚂 Vixen Horns 0.5 Gallon (2 Liter) Train/Air Horn Tank System/Kit - 5 Ports, 115 PSI with Gauge, Pressure Switch, Drain Valve, Compression Fitting, Hose, Thread Sealant - Compact VXT0500 by David Skyline

Unit looked good then necessary fittings installed with teflon as it was definitely necessary and necessary. I used the best Teflon I had on hand. But that didn't cause the "1". The tank has a defective weld pin hole on the fitting that contains the pressure gauge. A lot of water had to be sprayed at this point in order to find the cause of the pressure drop. The bad weld was powder coated so everything looked fine until I found a leak. THEREFORE, THIS UNIT WAS NOT PRESSURE TESTED BEFORE SHIPPING FROM THE FACTORY. INADMISSIBLE.
