THE BOSS Foam Cannon is the premier foam cannon on the market. It is crafted from premium stainless-steel and features our innovative Auto-Mix system. Like any fine-tuned equipment, it requires a level of maintenance. This rebuild kit includes everything you need along with a detailed assembly manual to guide you through the process. We have included 2 Stainless Steel Mesh Pills for restoring maximum foam output for two "refresh builds". The foam cannon is built to last a lifetime and this kit ensures it maintains peak performance.
