OPEN system containers are drums or totes (IBC) that do not contain a valve insert in the container’s bung opening; potentially, allowing dirt, debris, bugs, etc. to enter the container and contaminate the diesel exhaust fluid.

For open systems, use Drum Quick Pro (DQP) accessories.

DEF Packages do not include coupler systems.
You must choose a coupler kit to create a complete system for your fluid distribution needs.
