This Piusi USA Automatic Nozzle Meter is used for DEF. The diesel nozzle with meter is composed by an innovative technopolymer casing, a break-away system, a stainless steel spout and the Piusi K24 meter with +/- 1% accuracy. This kit allows you to transform a standard SB325 nozzle into an SB325 mis-filling system by simply fitting a different spout onto the digital meter fuel nozzle. The design features a reliable, ergonomic, and flexible shell that protects against weathering and UV radiation.
