The impressive Grex Tritium series airbrush is available with a 0.2mm, 0.3mm or 0.5mm nozzle size. Grex issues optional nozzle conversion kits allow you to modify any Tritium airbrush to any of those nozzle sizes. This TK-5 - 0.5mm Nozzle Conversion Kit includes all the necessary parts for the conversion, affording from a hair line to 50mL (2") spray pattern. Each kit is compatible with both the Tritium TG or TS airbrushes.
Grex® Tritium TK-5 - 0.5mm Nozzle Conversion Kit
The kit is packed in a clear plastic blister package that affords good protection to the contents. The package is thoughtfully molded with a slot for hanging the package. Inside are a wrench, instructions, two plastic capsules sealed with "Grex-green" rubber caps, and a baggie. Inside these containers are the:
• nozzle (protected by foam plugs)
• nozzle cap
• needle (the tip protected by a plastic tube)
Each component is milled to a high standard.
changing the nozzle
The instructions clearly guide you through the nine step procedure to swap nozzles. Anyone with a Badger or Paasche internal mix airbrush will be familiar with the process.
Changing out the nozzles is straightforward. Removing the needle and head are simple. However, due to its tight inset, removing and attaching the nozzle is time consuming. My big fingers were not able to screw the tip very far into the airbrush body, and careful use of the wrench was required to fully seat it. Otherwise, the entire assembly was done in about five minutes.
To demonstrate the performance of the 0.5mm nozzle in the video, I used Lifecolour acrylic paint. Though acrylic can be more challenging to use than enamel or lacquer, I use acrylic for health reasons; I have found that if an airbrush sprays acrylic well, it will spray other mediums better. In two demos the paint was straight out of the bottle, while one was thinned 2-to-1. The air was set at 20 psi and 40 psi. The acrylic paint sprayed nicely. Though I was not able to achieve a hair line pattern, you can see the fine width I achieved with this relatively large-pattern nozzle.
The TK-5 - 0.5mm nozzle performed very well. It affords the airbrusher to spray a larger pattern. The conversion kit has all the parts, and the parts are well protected by the outer and inner packaging. The tooling is fine. Screwing the nozzle into the airbrush body can be challenging due to the close tolerances.
I am very happy with the TK-5 - 0.5mm Nozzle Conversion Kit, and recommend it to any Grex® Tritium owner who needs a larger spray pattern.
