Hi,
I found this adaptor to connect corny poppet valves to a commercial coupler.
Its partway downe the page, 3rd from bottom

I would love to get one, but does anyone know of a brew shop that would stock such a thing.
I bidded up to $90 for a toohys coupler with corny plugs attached, but lost, Luckly, as this may be a lot cheaper
