Thunderbolt Posted April 14, 2022 Share Posted April 14, 2022 (edited) I currently have a 0.15 mm needle but am finding I need something larger to paint Tamiya’s fine primer out of the bottle. I am planning to obtain the 0.4 mm needle and nozzle. My question is: do I also need to buy a new aircap specific to the 0.4 mm needle/nozzle or can I just buy the needle and nozzle separately, using the aircap that came with the 0.15 mm? Based on my understanding of how an airbrush works, my answer to my own question would be yes.

thierry laurent Posted April 14, 2022 Share Posted April 14, 2022 As for other airbrushes the Infinity uses a combination of specific needle and nozzle tip. All other parts stay the same. Thunderbolt 1 Link to comment Share on other sites More sharing options...

denders Posted April 14, 2022 Share Posted April 14, 2022 Have a look here. I believe the Needle, Nozzle, and Air Cap need to all match. Harder and Steenbeck parts for Infinity (spraygunner.com) (I've no connection to SG, but I have purchased there.) Thunderbolt 1 Link to comment Share on other sites More sharing options...

My interpretation of the serial numbers indicates the same air cap works for 0.15 and 0.2 mm combos while a separate air cap is required for the 0.4 mm nozzle.

denders Posted April 14, 2022 Share Posted April 14, 2022 Actually, I have both an Evolution and an Infinity, which use the same pieces, and it's clear with the Mark I eyeball that the air caps have different size openings. I have both a Paasche TG (0.66mm) and a Creos 290 (0.50mm) which I use for primers depending upon the amount of primer to be painted. Link to comment Share on other sites More sharing options...

The airflow has to be proportional around the nozzle tip itself. I went ahead and bought a needle/nozzle/aircap set. thanks all scvrobeson 1 Link to comment Share on other sites More sharing options...
