If you have an air compressor and want to keep your car or bike tires inflated to the right pressure all year round, this is the right tool for the job. It is so convenient that removing/installing the tire cap takes about the same time as inflating/adjusting the pressure with this tool. If you don't know how it works, pull the lever a little to deflate (with fine/progressive deflation) and pull it all the way to inflate (no progressive inflation as far as I can tell, hence it is the fine tuning is mostly done). by blowing). ). It doesn't come with a quick connect nipple, so you'll need to buy one that fits your gear. The only thing I would like to change is to change the scale of the meter to make it easier to read small steps. in the normal range of car tires (30-50 psi). Most average people don't have tires that are rated for 180psi and most home compressors have a maximum pressure of around 130psi, so it would be nice if there was either a separate home version rated for a maximum pressure of 100-130psi designed, or modular/modular. change gauges.
