Ccvm product line

[Bamafig]

Most designs (2”) have a tee with a 2” funnel or reducer going to the product line (let’s say 1/2”). Could one not just braze in a 1/2” line straight to the 2” column? Thus eliminating the need for a tee and associated clamps, etc. The cost savings could be significant for those on a budget or truly small scale, hobby schedule. I’m not a metal worker so I don’t know if the reason for the tee is structural or just easier.
