Material requirements for direct contact with AdBlue

In order to avoid contamination of automotive urea solutions and corrosion of containers, pipes, valves, connectors, gaskets, etc., it is necessary to ensure that the urea solution of the vehicle is compatible with the material in direct contact at all stages of handling, transportation, storage and sampling.

How and Where is AdBlue Replenished

Refilling the AdBlue tank is not a do-it-yourself task. Although it is possible to purchase the urea solution at the retailer, it is generally available only through a dealership or service shop. The systems are designed with a capacity of several gallons which transforms into several thousands of miles. Under normal vehicle operating conditions, the AdBlue tank needs to be refilled only during regularly scheduled maintenance.
