i think thats easy-flow adapter in your link ..
theres no spiral thread on that adapter so you can only turn it so far
some ppl (including me of course) have managed to snap housing with it
the easy-flow male connector is 14/18mm .. dhgate glass is 14.4/18.8mm
..it fits ok but there could be tiny wobble
i use a (different) dhgate hydratube with plenty
heres a few dhgate glass videos - if you want to see what they look like working

he usually puts link in first comment
theres two delta 3 adapters
one replaces top half of c/u
one attaches to mouthpiece
theyre 3d printed silicone rubber - i have to say the c/u top replacement does wobble quite a bit..so youd need to use both hands all the time - but it functions well
the mouth piece one works nicely - quick and easy
the muzzmod is when you use dremel tool to cut off bottom of old crafty c/u to get the connector
and then glue on glass adapter
i havent done this
(..just noticed - theres one in the classifieds)
oh btw
all this information is fairly recent for me
..so i have knowledge but not necessarily wisdom
