APEX FAST DEFLATION TIRE VALVE, XL SET OF 4

Here’s how it works:

– Unscrew the valve stem cover and place your preferred pressure gauge onto the valve.
– Now simply slide gate cover out and watch your air gauge real-time as the pressure drops.
– Slide the gate cover closed and replace the cap…you’re done.

The toggle action allows you to precisely throttle the air to hit your exact desired pressure.
