UPDATE: I'm finally ready to go from an electric air compressor to a CO2 system. I called Milton customer service (very friendly and helpful people) to confirm it's safe. They have assured me that the Milton 553 is rated for a maximum of 160psi which is perfectly safe for my CO2 which runs at 150psi and their gear has been tested 40 degrees below temp so cold is not a problem either. the best air tube sensor I have ever used. When I was a kid, they were at every gas station in America that had an air hose. You are bulletproof. You can drive a truck over the handle and it will still work. I love having quality tools that I can rely on and this is no exception. I have this long hose because I can take it with me when I go off-road. After a long day at the track, it's great to be able to attach a tube to the valve stem and stand upright while I pump my tires back up. I can't tell you it was a game changer and I get a lot of envious looks from the other Jeep guys kneeling and holding the air liner in place while I rest.
