Diplomat v1.5 MTL RTA – Polished Finish Top Refill Bundle

The Top Refill Bundle brings modern convenience to the timeless elegance of the Diplomat. Built around the upgraded v1.5 deck, it includes the Churchwarden top refill system, enabling fast, clean refills without disassembly the deck from the bell. Smooth air delivery, rapid top-fill, modular design: this kit has it all.

Perfect for those who demand elegance without compromise.

At its core lies the air diverter from the RDL edition, featuring 24 precision-drilled 0.9 mm airflow holes, offering a more even and pressurized airflow. Combined with the classic 1- and 3-hole AFC rings, this configuration delivers ultra-smooth and whisper-quiet performance, no matter your draw style.

The base has been engineered with a dual-notch press-fit system, ensuring it never gets stuck on your mod — even under tight fastening. The new airpin system allows changes with the coil already in place, making adjustments easier than ever. Included with the deck are three airflow pins (1.2, 1.5, and 1.8 mm), with the 1.8 mm pre-installed.

For improved ergonomics, each AFC ring now features triple lateral cuts, providing a secure grip and effortless rotation during setup or adjustment.
