The Grex TK-3 0.3mm Nozzle Kit, for TG, TS, XGi, Xsi is a replacement and conversion kit for compatible Grex airbrushes. This is a nozzle kit designed for fine-detail airbrushing and controlled spray pattern adjustment. Model Number TK-3. If you need to restore spray quality, change nozzle size, or set up your airbrush for detail work without guessing at part compatibility, this is the kit that handles the core wear parts in one package.

What makes this kit useful is that it covers the three parts that directly affect atomization and pattern quality: the fluid nozzle, fluid needle, and nozzle cap. On an airbrush, those parts work as a matched set. Replacing only one worn piece can leave you chasing inconsistent spray, poor line control, or leakage. With the Grex TK-3 0.3mm Nozzle Kit, for TG, TS, XGi, Xsi, you are starting with the parts that matter most to getting the tool spraying correctly again.

The 0.012" (0.3 mm) size lands in a practical middle ground for a lot of airbrush work. It is small enough for hairline detail when you need tight control, but it also supports a spray pattern up to 1" (25 mm) when the job calls for more coverage. That range matters for users who move between detail passes and broader fill work without wanting an overly specialized setup that only does one thing well.

Grex lists this as a nozzle conversion kit, which makes it especially useful for owners of compatible Tritium and X series airbrushes who want to tune the tool for a different working style or replace worn spray components. Because it is built around Grex compatibility rather than a generic fit, you are getting parts intended for the matching airbrush platform instead of trying to make mixed components behave the same way.

The stainless steel construction is worth noting because these are precision parts that deal directly with fluid flow and repeated cleaning cycles. On small airbrush components, material quality is not a throwaway detail. It affects durability, corrosion resistance, and how well the parts hold up over time in regular use.

This kit makes the most sense for airbrush users who already own a compatible Grex model and want a known-fit 0.012" (0.3 mm) setup. That includes detail painters, hobby users, finish specialists, and anyone maintaining a Grex airbrush that has seen enough use to need fresh nozzle-side components. If your goal is reliable spray performance from a compatible Grex airbrush rather than experimenting with off-brand replacement parts, this is the straightforward route.
