Scuba Pro S620Ti - no gasket?

[hedonist222]

Noticed my S620 Ti has no gasket.

Is this normal for the s620 variant of the s600?

I noticed on two youtube s600 videos that there was a gasket.

Looks like it doesn't - based on this Scuba Pro promotional video

Hi Hedonist, what gasket are you talking about? This reg looks completely normal. I'm an instructor and a service tech.

Hi Dom.

Notice the white gasket in this photograph (from an S600):

The 620 Ti doesn't use that gasket to seat the diaphragm and diaphragm holder.
