Colby Rescue Valve, hex nut
Emergency valve stem repair. This valve stem goes in from the outside of wheel to replace a broken valve stem on all wheels with tubeless tires. With the hex nut this stem can serve as a permanent valve if desired and only needs a 1/2" wrench to tighten down in seconds. Steve prefers this model with the brass hex nut over the wing nut as the wing nut is plastic, he always has a 1/2" wrench anyway, and the wing nut may not work with some rims.
