The o-ring is the most important part and deserves the most attention during maintenance. Prevent the o-ring from drying out by lubricating it regularly with the original grease.

Before each dive, check the o-ring for dirt, damage, discoloration and hardening. If in doubt about the condition of the o-ring, it is better to replace it immediately.
