Inspection, Cleaning and Re-installation of the O-rings
Tools
Soft cotton buds that are free of chemicals or contaminants such as loose fibers.
Silicone grease supplied with the housing or other types of silicone grease specifically for underwater
camera equipment can also be used.
Procedure
The following procedure should be carried out on a clean, firm, level surface (e.g., on a table) to prevent
slipping especially when diving from a boat.
The O-ring can be extracted using the O-ring extractor tool that came with the housing, or push with
the flats of both thumbs or index fingers to gently stretch the O-ring on two adjacent sides thus
making a small loop protruding around the corner. The loop can then be grasped and the O-ring pulled
over the lip.
Clean the O-ring recess (the square groove where the O-ring sits) with a cotton bud.
Inspect the surface of the O-ring for contaminants and damages such as cuts or tears. This should be done
visually and by running the O-ring between thumb and index finger, sensing any textural abnormalities on
the surface.
If the O-ring is damaged or suspected of being damaged, discard it immediately.
Spare O-rings are supplied with your housing, or replacement O-rings can be ordered from 10Bar.
If the O-ring is contaminated, clean it with a clean cloth.
Re-inspect the O-ring after cleaning.
Once the O-ring has been inspected and verified good for use, apply and distribute evenly a SMALL
amount of silicone grease to the surface of the O-ring.
Replace the O-ring into the groove.
Run a finger over the O-ring to make sure it is seated properly.
