99.8% lead-free Brass okay?

[Big L]

Hi All!

In the very final stages of still building!

Need to add one final 2" ferrule so i can attach my snazzy reflux copper coil condenser in its very cool sight glass - i have one of these which i ordered ages ago..

Wondering if its okay to use this even though its brass? - its from a still site and says 99.8% led free but should i worry about that last 0.2 %?

Alternative is going back to the welding shop and asking them to braze a stainless steel one on
