bowtieman427: I suppose that it's possible that either your friend's Halcyon wing had a non-standard power inflater installed, the inflater hose on the demonstrated reg was non-standard, or the tolerance of the male nipple on the quick-disconnect fitting of the installed power inflater was out of specs (an issue described well by
laurin in the previous post). If it is a machine spec tolerance issue and your friend purchased the wing new, he would seem to have a case for seeking replacement of the power inflater from Halcyon Customer Service. Even if he bought it secondhand, I suspect that Halcyon would simply send him a replacement power inflater. My experiences with Halcyon customer service have been very positive.
If Halcyon Customer Service is unwilling to replace the power inflater assembly, a
new replacement K-style power inflater can be purchased from Northeastscubasupply.com for $25. It would be money well-spent.

eelpout: I want to thank you for raising this possibility. I am very serious about trying my best to disseminate accurate information in my SB posts. After all, I am just trying to be helpful.
Your last post made me question the accuracy of the info I've related in this thread. I am far from an expert on scuba inflater hose fittings, power inflater assembly construction/repair, and Halcyon gear. I'm just a recreational divebum who likes to know how to repair his stuff when it breaks, and I happen to own a Halcyon BC. From your profile info, it would seem that you have vastly more scuba experience than I.
That being said, your post provided the impetus for me to contact Halcyon Technical Services. I was informed that all Halcyon power inflaters (past and present) have standard quick-disconnect fittings. The company has never used proprietary fittings on their power inflaters. Furthermore, any standard inflater hose should work with the Halcyon power inflater. Coincidentally, Corey Smith was the one in Technical Services who shared this information. If you doubt the accuracy of this information (at least from your previous post you seemed to be convinced that I was wrong), I urge you to verify the info yourself by contacting Halcyon Technical Services directly.
If my previous posts sounded too heavy-handed (accusing the LDS of not being knowledgeable), I apologize for this. I'm going to extend them the benefit of the doubt with regard to knowing what types of inflater hoses mate up properly with certain power inflater assembly quick-disconnects. The LDS in question did have the equipment in front of them...and a simple trial-and-error approach would make the most sense in that case.
I also agree with your advice that a reasonable (and probably simplest) approach would be just to take the power inflater into the LDS and purchase an inflater hose that fits.
Given the info contained in this thread, it would be a pretty good assumption that a standard inflater hose should work with the OP's "new" Halcyon wing. It is a used gear purchase, however, so the possibility remains that one of the previous owners replaced the Halcyon power inflater with a non-standard power inflater.
Hope this post clarifies things...
