Hello. I have a rather unusual setup here and have just started using rotaries. It's a Thermaltake Tai-Chi with it's previous built in loop gutted.

Is is alright if they move while in open and closed positions?

Open:


(ignore the red splotches.... I don't know where they came from)

Closed:



and if you're wonder why the hell the tube goes behind the case:




Yes, I use 1/4" tubing Huge tubes in my rig have never been my thing.
so, is this usage fine? since the rotary moves everytime I open my rig. Those are Feser Rotaries.

Could I also get a recommendation for 1/4" tubing? I've tried Tygon 3603 which was fine and the silver tygon which was as tough as beef jerky and refused to bend in tight spots. Anything plasticiser free yet has less stiffness?
