Nauticam O-Ring for NA-503H/S Housing

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.
