Herbies tube damper tightness


How tight should Herbies tube dampers be?  I just tried to put an UltraSonic Rx damper on a 6h30 tube and it was so tight I thought it was going to crush the tube.  Is it normal for them to feel very tight during installation?

I have 3 integrated tube amps, a tube DAC, and a tube preamp, I've never found a need for tube dampers
