The o-ring is the most important part of an underwaterhousing and deserves the most attention during the maintenance. Avoid dehydration of the o-ring by regular appying grease with grease recommanded by the manufacturer. Check the o-ring before each dive for dirt, damage or discoloration.

When you are in doubt about the condition of the O- ring then it's better to replace it immediately. When you are not using the housing for a longer time then it is prefered to remove the o-ring and keep it lightly greased in a cool and dark place.
