DEF Fluid | Best Place to buy Diesel Exhaust Fluid
Diesel Exhaust Fluid (DEF) is a colorless, non-hazardous, and non-flammable chemical. If DEF comes into contact with skin it can simply be washed off with water. DEF is sensitive to chemical impurities and it is essential that it is handled carefully to prevent contamination. DEF is much more likely to be damaged by the materials it touches than to cause damage to equipment.
If DEF is contaminated it may cause the SCR system to malfunction. This means pumps and containers used for DEF must not be used for any other fluids. It is important that tanks, pumps, hoses and nozzles previously used for other products like diesel or lube oil are not used for DEF. The requirements for handling DEF are unique.
The shelf life of DEF is two years if the fluid temperature remains between 12°F (-10°C) and 86°F (30°C). Where DEF is stored outside in bulk tanks or totes then heating and cooling solutions are available to ensure it is kept within the correct temperature range. Cooling is usually achieved by insulation and ventilation. Air conditioning is not required.
The third part of the ISO 2224 standard gives recommendations and requirements for handling, transportation and storing DEF.
Certain stainless steels and various plastic materials are suitable for storing DEF. Carbon steels, copper, copper-containing alloys and zinc-coated steels should not be used. Contact your DEF supplier for a more comprehensive list of equipment and materials that are recommended and not recommended.
