Olympus o-ring for PT-053 / PT-056 / PT-057 [POL-053]

The o-ring is the most important part of the housing and deserves the most attention to maintenance. Avoid drying out of the O-ring by regularly greasing the o-ring with original grease from the manufacturer of the underwaterhousing.

Check the O-ring before each dive for dirt, damage, discoloration and pavements. When you are in doubt about the condition of the O-ring it's better to replace the o-ring.
