Aztek Nozzles for Acrylic Paint.

Tools, Techniques, and Reference Materials Painting and airbrushing

Dear all,

I have an Aztek A430 airbrush with the standard nozzles. Recently I bought two new nozzles for acrylic paint and found something different. The nozzles are the 9340C (General Purpose - Black) and the 9341C (High Flow - White). I found that when installing one of these two acrylic nozzles, the needle tip appears outside. Since no protection is available in the acrylic nozzle tip, the needle tip is exposed to damage or could hurt the operator. This problem does not happen with the standard nozzles, like 9304C, 9305C, 9306D and 9307C (and they have a tip protection). The two acrylic nozzles are working fine, but I am concerned with these exposed needel tips. Any hint on this?

Best regards,

Paulo Roberto

They are not protected on purposed, as the biggest problem with airbrushing acrylics is their fast drying time which often causes the airbrush tip to clog. The ‘open’ tips helps minimize this and I have confirmed that the ‘regular’ nozzles do clog more easily with acrylics. I use the TAN nozzle for fine spraying acryls and use a retarder/thinner to help minize clogs. My general purpse nozzle is the black one and having use it for 4 years now, never had an issue about damage. I even take out the needle and soak it in windex between use - the only way I can see damaging it is if you dropped the brush right on the needle.

Dear Waikong,

Many thanks for the explanation. Glad to know that this is the way they are supposed to work.

Best regards,

Is this the difference between the .05mm turquoise tip, compared to the white .50mm tip?
Apparently they both should be able to spray the same amount of paint correct?

Hi Paulo,

wow, it’s been quite a while since this thread was active! I personally never use the turquoise one, and as you said both should spray the same width. The only difference I see its the the turquoise one has a lip at the tip to protect the needle, this tends make drying acrylic paint more of an issue. So if you use it, you have to thin the paint down more - of course, that’s why I just stick to the white one.

Actually, I find that the black tip is the one I use 95% of the time for my 1/48th scale stuff. I can get a thin enough line and a broad enough pattern with that one tip. If I was doing maybe 1/72nd Luftwaffe squiggles I would need a finer tip of doing some 1/32nd plane I would need the white tip more.
