Grex Tritium airbrushes represents our premium line of double action pistol style trigger airbrushes. Their intuitive easy-to-use design appeals to beginners, yet their fine detail control and comfortable operation makes them appeal to professionals as well.

Grex Tritium airbrushes are a comprehensive line that can accommodate to your airbrushing preferences - top or side gravity, left or right hand, big or small reservoir, fine or wide spraying. These are feature packed airbrushes and you'll find the same reliable, high performance quality you've come to expect from any Grex product.

Grex Tritium airbrushes come in two forms - Tritium.TG, a top gravity version and Tritium.TS, a side gravity version. Each version is available in three different models with either a 0.2mmm, 0.3mm, 0.5mm or 0.7mm nozzle size.

Other than feed type, features of the Tritium.TG and Tritium.TS are the same. Which one to choose is really a matter of preference. See the advantages of each versions' feed type by clicking here.

The nozzle size on any of the Tritium airbrushes can be changed with optional conversion kits. See side panel for the different model numbers, contents of the airbrush sets and information on the Nozzle Conversion Kits.
