Iwata NEO Needle Cap

Was a bit worried about the fit, but it screws on perfectly to my NEO gravity feed and hasn't loosened up during use. The low-pressure coverage this setup provides is exactly what I needed for detailed work.

Fits fine on the gravity feed dual action, and it does keep the needle protected when I’m not using it, which is what I wanted. The cap feels a bit flimsy though, and it’s a little loose when snapped on, so I’m always checking it hasn’t fallen off mid-project.
