If your bottle can’t be tightened with your foam cannon Pro cap, you can contact our customer service, we will check and send a new cap to you if necessary. However, it takes some skills to take off the previous cap since the old cap is mounted with foam cannon body and they are glued. Please check the video for the operation. We suggest you immense the cap into the 100℃ hot water for three minutes first before taking off the cap, the high temperature would deactivate the glue, so that you can easily take off the cap. Please be careful when use the hot water.
If it is hard to take off the cap, please remove the brass bolt directly.
Before you put a little drop of Locktite glue on the metal thread, please screw the new cap on bottle. And then attach the new cap to the foam cannon body and ensure the logo is the on the direction you want.
Once the glue is dry, it is hard to take off the new cap or change the logo direction.
