    Even with just water and super low pressure, there are bubble flowing into the. The brush is super clean. I spent a lot of time and fine detail cleaning it four times. (Other then the bubbles, the airbrush feels great because it is clean).

    Not sure what I broke or how but, those bubble are causing problems.

    Simple question: what do I need to replace?

    Thank you for sharing your knowledge.

    What brush do u have? Normally that is a loose noozle cap or nozzle, and sometimes the needle not making contact with the nozzle because some debris or bad positioning!

    I bet is the needle not seating very good with the nozzle due to debris in the nozzle!

    Air bubbles in cup can mean a couple of things , Most times it is a cracked nozzle, other times it could just be the nozzle cap is not sealed properly.
    Did you remover the nozzle when you cleaned it.

    I have noticed that if water is on the outside of the airbrush it will bubble where the needle cap is screwed on... I tightened the needle cap as tight as I could. Do I need beeswax or something?

    If there are debris in the needle nozzle they have escaped four serious cleanings. I have a feeling that it is not debris but I do not have a microscope and light source to really know.

    On the Iwata, it is almost always going to be a poor nozzle seal. I do not recommend trying to tighten it, as they can be brittle, and break, but rather use a little wax, or chapstick on the threads before installing the nozzle. I know i just recently made a post with photo's covering this... you may be able to find it.
