Our Hose to Drain Adapter Kit allows a standard 5/8” water hose to attach to the drain cap for easy drainage of liquid debris away from the source. The large drain cap is compatible with our 6, 9, and 12 Gallon Wet/Dry Vacuums (0910, 0920, 0930). The smaller cap can be removed to attach a water hose. It also allows for a smaller diameter drain, making debris disposal less messy, helping avoid splashing. The gasket inside the drain cap prevents leaking even when the vacuum tank is full. The MILWAUKEE® Vacuum Hose to Drain Adapter Kit includes two attachable pieces.
