Airbrush performance hinges on nozzle size matching your application. These complete conversion kits let you adapt Grex Tritium and Genesis XGi/XSi airbrushes to different spray patterns and media viscosities without buying additional tools. Each kit includes precisely matched fluid nozzle and needle, plus nozzle cap, wrench, and installation instructions, everything needed for a clean swap.

Fine detail work benefits from smaller nozzles that atomize thin paints into controlled, narrow patterns. Larger nozzles handle heavier-bodied materials and cover broader areas efficiently, though the 0.7mm option demands more air volume than typical hobby compressors provide. Grex engineers these components as matched sets; the needle taper corresponds exactly to the nozzle opening for consistent spray characteristics and reliable paint flow.

Whether you're switching between fine illustration and basecoat coverage, or replacing worn components with fresh parts, these kits maintain your airbrush's original performance standards. The included wrench prevents overtightening during installation, critical for preserving the nozzle's delicate seating surface. Keep multiple kits on hand to match nozzle size to project requirements rather than compromising technique to available equipment.
