Customer Reviews (4.5 / 5 · 4 reviews)

Leo J. ★★★★★

The flavor difference on my NTSU RBA after fitting this cap honestly surprised me — richer and noticeably warmer. It seats firmly with no wobble, and the airflow stays smooth pull after pull.

Emily L. ★★★★★

Swapped this cap onto my NTSU bridge and the airflow tightened up just enough to pull richer notes out of my tobacco blends. Fit was snug on the first push but seated fine after that.

Claire ★★★★☆

Fits my NTSU RBA snugly and the airflow feels a touch tighter than the stock cap, which I actually like. Only gripe is the price for such a small piece, but the flavor improvement is real.
