Diplomat V1.5 MTL RTA DLC Final Run

Embrace the last chapter of the Diplomat legacy with our Diplomat MTL DLC, limited to just 300 exquisitely crafted units. This collector’s edition introduces the new v1.5 deck, a refined evolution featuring the air diverter from the RDL model (24 × 0.9 mm holes), while preserving the precise 1- and 3-hole AFC rings for ultra-smooth and whisper-quiet airflow control.

Thanks to its press-fit deck with dual notches, the base never sticks to your mod. The new airpin system allows airflow pin changes with the coil installed, and includes 1.2, 1.5 and 1.8 mm pins (1.8 mm pre-installed). Enhanced grip cuts on the AFC rings make rotation effortless, even under pressure.

This version is fully compatible with PEEK insulators and RDL airpins, as well as with any Diplomat tank or bell chamber. It ships with three bell styles (Duke, Freehand, and Rhodesian) offering varied profiles to match your draw and flavor preferences.

The SS316L body features a deep black DLC finish, paired with a SS Window DLC + Ultem tank, plus an included spare PC tank, and topped with our Kennedy DLC drip tip. Although it retains the same height and diameter as the standard MTL RTA, an internally relieved top cap increases capacity by +1 ml without altering its silhouette.

The bottom-fill system ensures maximum capacity and leak-proof performance. A final design choice made to honor function as much as form.

For the final act of the Diplomat, we’ve redefined every detail.
After this, the future begins.
