Why Use Caulk Tip Caps?

Leaving a caulking gun nozzle exposed between uses is one of the most common causes of wasted sealant. Even a short period of air exposure can dry out the glue tip, clogging the nozzle and forcing you to cut away the hardened material before every use. These simple rubber caps solve that problem instantly — just snap one on after each use and your sealant stays workable far longer.
