The FLO Locking Chuck is a specially designed device that locks on to a Presta valve to prevent air loss during inflation. The FLO Locking Chuck features an innovative dial design that creates a precision lock and a unique trigger grip allowing for a quick release without air loss.

The FLO Locking Chuck is plastic free and made from a combination of steel, aluminum and rubber.

Thread the FLO Locking Chuck onto any Schrader style pump to make inflation a breeze.

Why We Made This:
We designed the FLO Locking Chuck due to many frustrations with existing chucks when developing the FLO Air Gauge.
