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.

When water pressure acts on the O-ring, 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.
