Apex Designs Rapid Precision Valve (RPV) Standard Length - Set of 4

Drop your tire pressure from 35 PSI down to 10 PSI in under 15 seconds (based on a 35" tire). The Apex Designs Rapid Precision Valve (RPV) is a patent-pending, ultra-fast tire deflation system built for off-roaders and overlanders who want to spend less time airing down and more time on the trail.

Unlike traditional core-removal deflators or screw-on valves, the RPV uses an intuitive sliding gate cover. Simply attach your pressure gauge, slide open the gate mechanism, monitor your drop in real-time, and slide it shut when you hit your exact target pressure. The toggle action provides precise air throttling so you never over-deflate.
