the oring isnt "needed" if you want to use only the nylon setscrew
the oring is needed if you want to replace it, it slips on, adjust your setscrew so its flush with the threads (so there isnt a hole anymore) and it shouldnt get torn up
without the setscrew to fill the thread void, its a bunch of sharp edges and they will eat rubber orings
