The Grex TK-7 0.7mm Nozzle Kit is a replacement airbrush nozzle kit for select Grex airbrush models. This is a nozzle kit designed for restoring proper paint flow and spray performance on compatible Grex airbrushes. Model Number: TK-7. If your current setup is bent, clogged beyond recovery, or just worn out from regular use, this kit gives you the core parts needed to get the airbrush back into working shape.

What makes this kit matter is that it uses a matched 0.028" (0.7 mm) fluid needle and 0.7 mm fluid nozzle. On an airbrush, that match is everything. When the needle and nozzle are sized correctly to each other, you get more predictable atomization, smoother material flow, and less frustration chasing inconsistent spray patterns. For users spraying heavier materials or covering more area than a fine-detail setup would allow, a 0.028" (0.7 mm) configuration is the practical choice.

The Grex TK-7 0.7mm Nozzle Kit uses stainless steel components, which is the right call for a wear item like this. These are the parts that take the abuse during cleaning, reassembly, and day-to-day use. Stainless steel helps with durability and gives you a solid replacement option for keeping your airbrush serviceable instead of sidelined.

This kit is built specifically for Grex TG, TS, XGi, and Xsi models. That model-specific fit matters because airbrush parts are not one-size-fits-all. A nozzle kit that is actually made for the platform saves you from guesswork, poor sealing, and spray issues that come from trying to force a close-enough part into the wrong body.

Grex also includes the small pieces that make the swap practical. Along with the needle, nozzle, and nozzle cap, the package includes a nozzle wrench and instructions. That means you are not just buying a single replacement part. You are getting the core service parts needed for the changeover, plus the tool and guidance to handle the install correctly.

This kit makes the most sense for painters, modelers, finish users, and hobby or shop users already running compatible Grex airbrushes. If you need to restore performance on a Grex gun rather than replace the entire airbrush, the Grex TK-7 0.7mm Nozzle Kit is the clean, sensible repair path.
