Husky SST stainless steel DEF nozzle with mate guard and handle cover

Overview

SST DEF is Husky's stainless steel Diesel Exhaust Fluid nozzle for full-service and self-service stations. It shuts off when the DEF tank is full, and its modular design makes it easy to clean when urea crystallises.

Husky says it is constructed from materials 100% compatible with DEF. It comes standard with a mate nozzle guard and handle cover, and a magnetic Accufuel spout is available as a safety feature against misfuelling. The inlet is 1 inch BSPP or M34 x 1.5.
