Note on the O-ring

What is an O-ring?

• An O-ring is part of the water-proof packing that is used on underwater cameras, watches, and
other diving equipment.
• The O-ring acts to preserve the waterproof qualities of the marine pack and other equipments.

How the O-ring waterproofs

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.
O-ring maintenance is very important. If O-ring maintenance is not
followed according to instructions, a water leak may occur and
cause the marine pack to sink. Waterproofing is achieved by
perfect sealing of the O-ring to the entire contact surface.
