O-ring between beer line and tap?

[Deam]

I'm ready to tap a commercial keg for new yearseek: I know let the flaming commence), and I'm wondering if I need an o-ring between the beer line and the Sankey-D coupler? I've only ever used the corny kegs so this is new territory for me... Pictures attached.

I'm sure this is a simple question, but I couldn't find an answer on the forums. Which more likely means I couldn't find the proper search strings

Thanks in advance!

yes.
You could probably make something if you were in a bind, but there's definitely sposed to be a gasket there ...doubt it'll seal without one.

Happy new year
