SturdyONE Airflow Pin Kit

The SturdyONE Airflow Pin Kit from Sturdy MFG gives you additional airflow options for your SturdyONE RBA. This kit includes four spare airflow pins in different sizes: 0.8mm (new), 1.2mm, 1.5mm, and 4mm. Swap between pins to fine-tune your draw from tight MTL to more open restricted styles. Everything arrives in printed ziplock bag packaging for easy storage.

Note: Batch 1 RBAs came with the 4mm AF pin as standard. All other batch SturdyONE RBAs include 1.0mm, 2.0mm, 2.5mm (installed), 3.0mm, and 3.5mm airflow pins as stated on the box.

Why Choose the SturdyONE Airflow Pin Kit?

The SturdyONE Airflow Pin Kit expands your airflow options beyond the standard pins included with your RBA. The 0.8mm pin gives you an ultra-tight MTL draw, while the 1.2mm and 1.5mm options sit between the stock sizes for more precise tuning. The 4mm pin opens things up for Batch 2 and 3 users who want a looser draw. Having multiple pin sizes lets you experiment and find your perfect airflow without buying individual pins separately.
