Review on 🔧 Milton Heavy-Duty Tire Pressure Gauge and Inflator with Lock-on Chuck S-568, Easy-to-Read 0.1 Display, Ergonomic Pistol Grip Handle, 20” Hose, 255 PSI Max Pressure, 1/4" NPT (PSI, kPa, Bar, and kg/cm2) by Scott Reid

After reading the posts, I was worried about a leak. There are no leaks and here is what I did. Instead of the cartridge I sent, I installed a quick coupler. I used teflon tape on the threads. Used Teflon tape on the threads of the hose leading to the pistol grip. The real problem was the power supply cutting into the bottom of the pistol grip. The plastic on the handle prevents the tap from entering the steps at the right angle. I took a sharp knife and cut the plastic off the top of the thread about 20-30 degrees. This gives the necessary clearance to avoid overcutting the feed thread. The machine works great, no leaks.
