This airbrush adapter is mostly used for when you have an airbrush compressor with the larger G1/2 coupler but your airbrush hose has an G1/8 coupler. It also fits our separate airregulator unit and our RUBY spraygun if you want to use an hose with a G1/8 coupler.

Note, all our Hobbynox airbrush compressors have the normal/smaller G1/8 coupler so it's not needed with any of them.

Male Threads: G1/8 (BSP) - fits all of our braided airbrush hoses with a G1/8 (BSP) female coupler
Female Threads: G1/4 (BSP) - fits your airbrush compressor that has an G1/4 (BSP) male coupler
The female threaded part has an o-ring seal inside it = no thread-tape needed
