Bubbles in my suction cup.

[The Chef]

Right having slight issues with my airbrush. I'm getting bubbles coming up through my suction cup and I cant get a small spray. I've stripped and cleand the brush throughly and still the same. Any Ideas? Bugging me big time.

Thank you

you got a slight blockage in either the tip or where the needle passes through to the head of the brush, you can clean the brush with a pipe cleaner and some thinners/motor cleaner, and you may have to 'create' a nozzle cleaner to. Also soak it in airbrush cleaner?

clean it again, the slightest bit can affect it. also make sure all parts/threads are tightened properly

I've cleaned it twice but I'll have another go. Used pipe cleaner and airbrush cleaner. I'll go have another go.

[jonmiller]

like said, make sure all the parts and threads are sealed well too.
bit of wax/sealer on the threads to make sure there are no air leaks etc

Also clean the really small parts at the end too. They're the main parts to get blocked. May need a scraping out. I use the blunt end of the needle. You'd be surprised how much gunk can collect in there.

Must have had a hair line fracture and I cleaned it and cleaned it nothing in it anywhere. Went to undo the nozzle and ti came apart, broken thread from nozzle. So I've ordered a Iwata today the CR 5 on Jon's advice, he's not steered me wrong yet I can only hope they are a little more robust and easier to clean.
