This part will lock the one-way valve onto the ultralight cap. Pressure or squeezing the bottle can cause the valve to pop out of the cap. This prevents that from happening.
The bump of the valve lock should be up. Snap the valve lock onto the barb bottom from the side of the cap, then rotate over the valve. Push the hose all the way down to the valve lock.
This shouldn't be complicated.
