Nauticam O-Ring for NA-G7X/G7XII/RX100III/RX100IV/RX100V/RX100VI/VII/G7XIII/G5XII

O-rings are wearing parts. Most manufacturers recommend changing the O-ring at least once a year. Please remember to check the O-ring after each use of the underwater housing: Checking the O-ring Cleaning the ring groove Lightly grease the O-ring *. * Do not use too much grease, because the grease itself does not seal. It is only used to maintain the pliability of the O-ring. Important: Colored O-rings (red, blue, yellow, etc.) are made of silicone. The O-ring grease used for greasing must therefore never contain silicone, as this would be built into the O-ring and the thickening O-ring would no longer seal properly.
