When an airbrush starts misbehaving, the nozzle is often the culprit. A worn, cracked or paint-blocked nozzle can cause spitting, pulsing, uneven spray patterns and sudden loss of control—especially when you’re trying to do smooth fades or clean coverage.

The AirCraft SG-A138-03 nozzle is a replacement part made for the AirCraft SG-A138 airbrush. It’s the right fix when cleaning no longer solves the problem, or when the nozzle has been damaged by accidental knocks or over-tightening.
