That looks like Capricorn tubing. It’s got a 1.8mm, not 2mm, inner diameter.

I used to regularly run into cheap filament that varied up close to 1.8mm in diameter that would get jammed in the tubing.

When I did, tossing the roll was my only option.

Capricorn is great for reducing filament backlash and printing flex, but requires very consistent filament.
