Our hose to drain adapter kit allows a standard 5/8 in 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 gal 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.
