Micro-Mark エアブラシ用エアラインアダプター、M5x0.5 BSPオスから1/4インチBSPメス

This adapter let me finally hook my airbrush up to a standard compressor without any adapters, and the M5 thread fit perfectly on my brush. No leaks at the connection, which was my biggest worry.

The threads on this little adapter are machined perfectly, so it screwed right into my compressor without any wobble. I was worried the M5 to 1/4 inch conversion might leak, but it sealed up tight on the first try. Finally got my airbrush hooked up without needing a whole new hose.

I was pleasantly surprised how smoothly this adapter connects my spray gun to the hose—the M5 male threads fit perfectly into my airbrush without any wobble. The only minor gripe is the adapter is a bit short, making it slightly awkward to tighten in tight spaces, but it works great overall.
