Internal diameter 1.8 millimetres, outer 2.6 millimetres, 37 millimetres long: that is the dimension set of standard 1.75 millimetre filament tubing, sized so the bore continues uninterrupted across the joint instead of stepping at it.

It is also the correct part for repairing a tube run that has been cut short during a nozzle change, which is the most common reason a printer starts under-extruding for no apparent reason.
