Using them prevents leaks later on, clamping the tubes.

I have fixed two leaks in pitot static systems over the years. Both were caused by clamped fitting. That's when I started to take seriously the instruction to never clamp pneumatic tubes with anything. Silicon tubes are idiot-proof, PVC tubes age and may become loose if fitting is connected frequently, the fix is to shorten the tube few centimeters and then plug it back.

Yep, use silicone tubing. It doesn't age like the clear plastic stuff, and remains
easy to push on and pull off. My glider came with the plastic lines for the pitot,
static and TE, so I shortened them, then added back the length needed with a
barbed plastic fitting and silicone tubing. No more tubing problems, and easy to use.
