Abstract

A method of adapting a threaded connection to an aerosol can, including providing a lower fitting, an upper fitting including a male thread, and a seating radius configured to conform with a curled lip of the aerosol can, a crimp ring, configured to rest between the lower crimp ring seating surface and the upper crimp ring seating surface, inserting the lower fitting into the crimp ring and the upper fitting, thereby forming an adaptor assembly, inserting the adaptor assembly, lower fitting first, into the aerosol can, the aerosol can comprising an inner surface, pulling the lower fitting through the upper fitting, thereby compressing the crimp ring in the axial direction while simultaneously expanding in the radial direction, thereby making contact with the inner surface and fixedly installing the adaptor assembly in the aerosol can.
