23*1.5mm silicone O-ring

Maybe my flashlight tail cap threads have a issue but on my L21B these o rings while unscrewing tail cap grip into it and then snap, I have to be extremely careful and press down while unscrewing to avoid this and I also used lots of grease but the issue persists, for now I have put my sofirn if22a o-ring on my L21B tail cap and that one is thicker and better quality and it doesn't grip, I think this o ring is great but it could be more durable... I don't have any other options. I have gone through 2 o rings in the past month alone. I think it maybe user error but I feel sofirn o-rings are better quality. These are slightly less.
