The right nozzle for gas Plastic Pump(KEXON) that also stock DEF (Diesel Exhaust Fluid) is important because of the nature of DEF. This all important fluid that must be used in trucks and other vehicles that run on diesel may be simple and reduce polluting emissions, but it can corrode certain materials like carbon steel, aluminum and even some kinds of plastics.
Obviously the DEF nozzles used in gas stations are different from those that dispense gas or CNG.
Diesel Exhaust Fluid has certain characteristics and the nozzles are made to handle and dispense DEF. Basically there are two different kinds of DEF pumps: hand pumped (pneumatic) and electric. Hand pumps are used for barrels and jugs so most large gas stations use electric pumps that are more expensive, but are also more efficient and easy to use.
DEF nozzles are different from the nozzles that dispense other fuels in some aspects. They have certain features:
Made of stainless steel or nickel plated aluminum.
Come with a magnetic lock system that enables the nozzle to stick to the DEF tank in the vehicle.
Size and magnet prevents the DEF nozzle from going into the fuel tank.
It is important that gas station owners and operators put in care and thought when selecting the right DEF nozzles to dispense the fluid. Different sizes and types of DEF nozzles are available with manufacturers of specialized petroleum and gas dispensing systems. Many brands are available and, depending on the cost, you will get more or less features.
