Newsflash! Underwater cameras never let in water, it is o-rings that cause floods!
The seal between mating surfaces on your kit is made by o-rings (soft rubber rings that flatten out under compression to fill the gaps). You will find o-rings on the main seal, the port/lens and on all control shafts.
To maintain user serviceable o-rings you should...
- remove them (without using sharp tools that might damage them)
- clean the o-ringThe rubber ring that seals underwater camera equipment. groove
- inspect them for damage
- grease them lightly with approved silicon grease by running them through your fingers (without stretching them)
- only grease them till they shine, do not use excess grease (it just collects dust)
- replace the ring, check for hairs, dust, and other material that may bridge the seal
- close the mating surfaces together
- open and check again!
- don't open the seal again before you dive!
Control shaft o-rings are not user serviceable and it is easy to forget them
because you can't see them. The problem with control shaft o-rings is that, inevitably,
crystals will form as seawater dries out, and these can abrade the o-ring when you
next operate the lever. If
your controls become 'sticky' i.e. do not spring back into position when
operated this is indicative of an o-ring problem! Take your housingA casing or box with waterproof seals designed to contain a camera or other equipment in such a way that it can be used underwater. to a repairer.
