Hello guys ! I am well aware what those number mean and that the one is 4mm shorter than the other ,but i dont know what is the difference in the OD/ID of the narrow end of the joint . Can someone who has 19/22 ,for example a milaana stem measure the OD/ID for me ?

Ok.. guess i didnt enter the right parameters in my google searches.
19/22 Glassware is a taper ground joint standard used in laboratory glass. The 19/22 glassware is made of borosilcate glass and is manufactured according to ASTM E676. 19/22 has a 19mm diameter and 22mm tapering joint length. The small end of the taper is 16.6mm in diameter and the diameter a the top end of the taper is 18.8mm.

So it appears that the difference in the tip diameter is just 0.4mm ? It still would be nice if someone can confirm with measurements,online date can varies. .
Never the less i consider now the 19/22 better choice for a bowl than the 19/26 cause it has straighter airflow.

There is no standard for the inside diameter of the joint. This has created issues for using screens of a set specification in deployment into an area that lacks any specification.

Sometimes they work, sometimes they don't, sometimes you need a lot of force to get something to work and can offset the the layout of the screen from sitting symmetrically in the joint and sometimes nothing works.

Thx ! I actually found an old Arizer elbow and i measure 22mm long so it is 19/22 . Measured 0.5 mm difference.. now at a second thought its role is a bit unimportant as far as airflow goes, i tested and detected zero difference in performance. :).
Yes ID is variable due to various glass thickness used in gongs.
