An empty pressurized can that has been lying around my garage and a handy air pump gave me another idea to make my dusting job a lot easier.
And.. of course, a valve from discarded bicycle inner tube will definitely complete the project. Ensure to sandpaper, and clean the area to be soldered. Don't forget to remove the inner stem of the inner valve since the stem have some plastic parts. I recommend to using at least 50 watts soldering iron.
I would stay safe with 60 psi of pressure.
