What is the O-ring?
≥
The O-ring is a waterproofing packing used for underwater cameras, watches and
diving equipment.
≥
The O-ring keeps the Case waterproof by sealing the gap between the rear case
and the front case.
∫
How the O-ring keeps the Case waterproof
The gum comes into contact with the sides of the Case making the
Case waterproof and stopping water from entering from the gap.
When the O-ring is crushed by water pressure, the surface of
the O-ring expands and the Case is sealed more tightly.
The O-ring prevents water leakage by coming into uniform
contact with the sides of the Case. Therefore, good care of the
O-ring is very important. Incorrect care of the O-ring may
cause water leakage.
