• An O-ring is part of the water-proof packing that is used on underwater cameras,

watches, and other diving equipments.

• The O-ring acts to preserve the waterproof qualities of the marine pack and other

equipments.

The surface of the O-ring contacts the rubber to prevent water from entering the gap.

When water pressure acts on the O-ring, the contact surface area of the
O-ring expands to increase the force acting on the groove on the marine pack.

Avoid setting the O-ring in dusty or sandy locations.

Remove the O-ring.
Do not use pointed or metal objects to remove the O-ring. These objects might
scratch or damage the marine pack groove or O-ring.

Inspect the O-ring.
•Fully check the following, and wipe off with a soft cloth or tissue paper.

– Check for any dirt, grains of sand, hair, dust, salt, thread scraps, etc.
– Check for any old grease.

•Lightly run your fingertip around the O-ring to check for any unapparent

dirt.

•After wiping the O-ring, take care to prevent any cloth or tissue paper fibres

from remaining on the O-ring.

•Check the O-ring for cracking, skew, distortion, fine splitting, scratches,

sand-biting, etc. Replace cracked or scratched O-rings.

Inspect the O-ring groove.

Grains of sand or hardened salt sometimes get into the groove. Carefully remove
them by blowing with an air spray or by wiping them with a cotton wool bud.
Prevent fibre scraps from the cotton wool bud from entering inside.

Also, inspect the contacting surface on the other side of the O-ring in the same
way.
