Husky POLY DEF nozzle
Lighter polymer DEF nozzle, ISO 22241-2 compliant.

Overview
POLY DEF is a polymer Diesel Exhaust Fluid nozzle for full-service stations. It shuts off when the DEF tank is full and is lighter and less expensive than comparable stainless steel nozzles, with a stainless steel spout for durability and a replaceable spout.
Its flow characteristics are shaped to reduce crystallisation of DEF, and it complies with ISO 22241-2:2006. A magnetic Accufuel spout is available to prevent misfuelling, and the two piece polymer EZ Lever reduces the force needed to open the main poppet.
