^ I made sure my new one was twist locked. That was the hardest part. But I got it. I didn't want it coming off. I noticed some just dremeled it or whatever but I massaged it on, fully locked. Will yours blow apart? Doubt it. it's a vacuum system. could it vibrate lose or have some vacuum leak, yes.
