I use this cartridge when I put airplane tires in my hay wagon. The van has split rims and there is always a risk of inflating the split rims. So this cartridge allows me to secure the end of the tire and get it to a safe area to inflate. The Milton gauge is the best of the best and I have a similar one with a shorter tube that I use to inflate my tires regularly. But the clip at the end works very well and I used this cartridge this morning. Don't waste your money on imported gauges that mimic Milton. You will end up buying a Milton!
