While most standard clip on or or push on chucks only open the Schrader valve about 50%, our High Flow Chuck was designed to open the Schrader valve 100% which means more air flow allowing you to air up faster.
The High Flow Chuck was optimized to work best with our Rapid Precision Valve but still works great with standard Schrader valves.
NOTE: This air chuck will NOT work with multi-hose air down/up systems, which require a closed flow chuck. The Apex High Flow Chuck is OPEN FLOW.
