How to place a crack and crevice tip on aerosols

The manufacturers of these aerosols do not install the nozzle on their cans so as to prevent leakage and accidental discharge of the product during shipping. To install the nozzle follow these steps. Use gloves or wash your hands afterwards.

 1. 



Line up the hole on the underside of the nozzle with valve stem on top of the can.



 2. 



Point the injector straw away from you and press down swiftly and firmly and you will feel the nozzle slip into place ( some hear a click).
The aerosol can will spray when you do this so it is best to do it outside.
