Well, we took a trip to the local hardware store and found the item, it's a....
Pope BSP nut & tail, they come in 20 & 25mm, under $3Aus. Since I'm not that far into the build of the vest, I haven't looked into it yet, but if anyone can let me know which dimension is correct, I can buy them and ship them to you guys at cost of item plus postage, packaging, plus Paypal fee's (4% I think) . I won't take a fee, what I pay is what you'll pay. I hope this helps.
Thanks!!! If my hoses are more than 1" they're not MUCH more. I'm excited now... We were just getting ready to go in search of new connectors for my brand new chest armor, too. Yeah, I think those will do
