probably because the vacuum of space is way more extreme than inside the tube which would cause pressure on the seals

Vacuum tubes typically have an internal pressure of less than 0.001 atm, sometimes much less.

Any seal that can withstand a pressure difference of 0.001 atm to 1 atm from the outside can almost certainly withstand a difference of 0.001 atm to 0 atm from the inside.
