Narrative:

Approximately 15 mins south of flori intersection; right hydraulic system began leaking fluid. Pumps were shut off in accordance with QRH procedure. Discussed possible diversion airports with dispatch. First officer and I both agreed no emergency should be declared since the hydraulic system was still functional; but agreed flight should not continue to ZZZ per QRH warning regarding loss of additional system or engine failure. Elected to land ZZZ1 without incident. Callback conversation with reporter revealed the following information: the reporter stated the loss of the right system hydraulic fluid was caused by 2 worn or failed o-ring seals in a hydraulic module. Identify and location of module unknown.
