Yeah, this should work fine. Just make sure not to under extrude and do at least 3 perimeters with enough infill. Make sure that there is no gap between perimeters.
I made a few 3D printed parts for pneumatics applications (pneumatic muscles) and they work up pretty well.
I didn’t know these vacuum pods, I think I’ll print some right away, thanks !
