When recently installing a new bottle o-ring on my RAW HM1000x, I was concerned about damaging the o-ring when rolling over the sharp threads.
I used an old Harley Davidson trick of applying a couple of wraps of Teflon sealing tape over the threads. Lightly lubed the o-ring and slid it on. Works just fine.
