Macnaught BOP205X 16-55 Gallon Battery Operated
DEF / Oil Stem Kit

The Macnaught BOP205X Stem Kit is a versatile battery-powered delivery system engineered for fluid transfer from 16 to 55 gallon containers. Designed for maintenance, service bays, and industrial environments, this stem kit delivers controlled dispensing of a wide range of commonly used fluids when paired with a compatible 18V powerhead.

Suitable Fluids

This stem kit is purpose-built to handle a broad set of shop and industrial liquids. It performs reliably with:
