Abstract
An adaptor for a caulking tube nozzle, the adaptor including a reducing coupling having a large end secured to the caulking tube nozzle and a small end which is threaded, and a cap having threads for engagement with the threads of the small end of the coupling to thereby cap and seal caulking material within the coupling when the caulking tube is not in use. In one form the large end of the reducing coupling is internally threaded for self-tapping engagement with the caulking tube nozzle, and the small end is externally threaded for engagement with internal threads in the cap. In another form, the large end of the coupling is formed integrally with the end of the caulking tube.
