Ive came across a so/so vid which may explain it for you.
https://youtu.be/XXf_uaRK6o4Oh, its my vid by the way which i did some time back.
I use john guest fittings and that seems ok on the pole which i use the uni valve on (which happens to be the facelift pole in the vid). I use a stiff rhino hose designed for the univalve as it doesnt stretch as much as the usual pole hose. However this is not my every day pole as I use this for my trolley. So day in/day out with a john guest fitting may or may not work. Its fine for what I use.
The main kit is called the "slick connect" but to me it seems chunky,
