The needle is what turns an airbrush from “sprayer” into “precision tool”. It controls paint flow at the exact moment you pull the trigger and works with the nozzle to deliver a stable, repeatable spray pattern.

When a needle is bent or worn, you’ll often see spitting, inconsistent spray, poor line control, or paint pulsing—especially during slow, controlled passes. The AirCraft SG-A130K-34 0.3mm needle is a genuine replacement part for the AirCraft SG-A130K airbrush.
