Is this a common practice to leave them off?
Is it ok. to not use them?
Yeah, I don't use either one. The Cap, just because the valve screws down and theres no place for dirt to get into them, and the ring, if you tighten them too much the valve comes out of the tube, I had it happen like 3x this last summer, the LBS mech said you don't even need them, so I don't use them to try to keep the tubes intact.
