Funnel / Inject Tire Prep
To use as a funnel: Thread injector tip onto the valve stem - attach hose to the end of the funnel - apply the hose clamp to prevent tire prep draining into the tire - fill injector tube to the desired amount - release hose clamp. (Hose clamp will allow accurate measurement and will not allow tire prep to release into the tire until you release the hose clamp.)
