Automatic all-top ventilated set

All-Top automatic inflation vent set with adjustable air pressure gauge and settings that can be fixed according to the user's preference without the need to stop and monitor each time. Features: Innovative: This set allows you to ventilate tires in a short period and you will not have to wait and monitor tire pressure. The vent valve will automatically stop at the pre-set PSI value. Accuracy: Each tire air vent device is calibrated individually, however, a +/- 2 PSI is acceptable. The air vent set is designed for quick air adjustment on off-road, but not for precise vehicle tuning. Adjustable: No tools required. The tire air vent device comes with a transparent measuring screen, set the desired air pressure, and it stops releasing air when reaching the PSI value, simply by turning the air release cover (where the logo is). Adjustable range from 30 PSI to 10 PSI. Packaging: This set comes with 4 air vent valves and one zippered bag. It will be the perfect tire deflation tool for your friends on off-road, trucks, power sports, SUVs, or RVs.
