You will get 180' of phase shift, or a complete polarity inversion, beginning with the signal inverted at DC, and rotating through to non-inverted above the RC tuning frequency. Two in series will give you 360' of phase shift..

Are you trying to make an effect? or something to compensate for say the delay between a mic and direct feed from a bass cabinet? For that application you want to tune the RC pole for a relatively LF, and be aware it will only correct for one spot frequency, not all frequencies because it isn't a real delay.
