AdBlue Only Labels - Safety Signs by Caledonia Signs

Clearly indicate that a vehicle or its diesel exhaust fluid (DEF) tank is designated exclusively for AdBlue, a urea-based solution used in selective catalytic reduction (SCR) systems to reduce nitrogen oxide (NOx) emissions in diesel engines. These labels prevent contamination of the AdBlue system, which is highly sensitive to foreign substances like diesel fuel, oils, or other chemicals. Using the wrong fluid can damage the SCR system, leading to costly repairs and increased emissions.

These labels are particularly important in commercial vehicles, trucks, buses, agricultural machinery, and construction equipment that use SCR technology. By prominently displaying “AdBlue Only” labels near the filling point or on the tank, drivers and maintenance personnel are reminded to use only the correct fluid, reducing the risk of errors during refueling or servicing.

The labels also help comply with manufacturer guidelines and environmental regulations, as SCR systems are designed to meet stringent emissions standards. Proper labeling ensures that operators maintain the system’s efficiency and keep vehicles environmentally compliant while avoiding unnecessary downtime caused by system contamination.

Overall, AdBlue Only Labels promote safe handling, prevent costly damage, and ensure environmental compliance. They should be placed directly on or near the AdBlue filler cap or tank, in clear view of anyone refueling or servicing the vehicle, to maximise visibility and prevent mistakes.

Materials Explained

Below is a more detailed description of the materials this particular safety sign is available in. Helping you decide which sign option is most suitable for your application.

Self-Adhesive Vinyl: Self-adhesive vinyl is easy to apply and it is budget-friendly. Its adhesive backing allows for easy application to a variety of surfaces such as glass, metal, plastic, and painted walls, which simplifies installation and reduces setup time. Self-adhesive vinyl provides a clean, professional finish that suits many indoor environments including offices, retail, industrial sites, and vehicles. It is more affordable than many other material types and allows for custom shapes, colours, and graphics
