I have the Sherwood Gemini - and out of sheer curiousity - I was able to take the "quick connect" connector off of the supplied Sherwood hose. Once the connector is unscrewed, the hose that is supplied with the Gemini is a standard regulator hose. (It just unscrews from the end like any octo inflator adapter)
I have already ordered a 30" blue Miflex hose from Phil to try with this setup. I will post my results / photo's once I get the hoses.
Now, my wife on the other hand, has an oceanic AirXS 2, and her adapter does unscrew, but, the hose has a male connector on each end, so, as of right now I'm not to sure how I will get her a MiFlex for her octo.
**edit** I disassembled the hose, and took a photo, I also switched my Cressi Regulator and the Octo connector and did a test - and it works perfectly. I have added the photo of the connector disassembled.
Of course... this is just what I've found, your miles may vary.
