Review on 🔌 Tru-Flate 17-351 1/4" Female NPT Direct Air Line Chuck With Shut-off: Efficient Tool for Air Compressors by Samuel Hansen

See the attached photo. The top cartridge is a Tru-Flate cartridge. The bottom cartridge is a cheaper cartridge I've had for decades. Note the triangular structure in the lower cartridge. This will keep the roll pin centered so it can push in the tire valve pin. Because the Tru-Flate chuck lacks this centering structure, the chuck pin floats freely in the chuck and is extremely difficult to get it to press against the tire valve pin. If you cannot push the tire valve pin, you cannot inflate the tire with air.
