Anyone know what the clear plastic/silicon/rubber fluid head cover that these brushes come with is called ,I can find no mention or part# anyplace of that item and I would like to find a replacement
TIA

Iwata doesn’t sell the protective cap you are looking for as a replacement part that I know of. The manuals don’t address it so there is no part number assigned. You might try contacting Coast Airbrush since they have been an Iwata dealer for years.

Good luck in your hunt,

Although this one is made for a Badger, it may also fit
an Iwata.

Badger in the USA has this item in their catalogue and sells for $ 2.10.

Cheers,

This may be slightly off topic, but get one as soon as you can. I dropped my Badger, on concrete. The protective cap saw it survive, with no ill effect. This is unlike the Iwata I dropped that didn't have one. Cracked halfway down the length of the body.
