Products Description
Underwater camera housing O-rings are sealing rings used in underwater photography equipment. Their main function is to prevent moisture from entering the camera housing and protect the camera from damage by water, sand, and other contaminants.

Main functions of O-rings
Waterproof seal: O-rings form a reliable seal by tightly fitting the contact surface between the housing and the accessories, preventing water or other liquids from entering the camera.
Protect equipment: When taking photos or videos underwater, O-rings effectively prevent water from penetrating and avoid damaging electronic components, thereby extending the life of the equipment.
Versatility: Besides their basic waterproof functions, O-rings seal key parts such as control panels, lens doors, shutter releases, etc., to ensure they operate normally underwater.
Material and Lubrication
- Material: Underwater camera housing O-rings are usually made of silicone rubber, nitrile rubber, and other materials, which have good elasticity, water resistance, and chemical resistance.
- Lubrication: To ensure the sealing performance of the O-ring, special grease needs to be applied to its surface. Grease can help the O-ring fit the sealing groove better and reduce friction and wear.
Maintenance and Inspection
1. Cleaning: Use a clean, lint-free cloth or paper towel to clean the O-ring and its sealing groove to remove impurities such as dust, sand, hair, etc.
2. Inspection: Regularly check the O-ring for scratches, cracks, or deformation. If any problems are found, the O-ring should be replaced immediately.
3. Storage: When not in use, the O-ring should be removed from the camera housing, cleaned, and greased with an appropriate amount of grease, and then stored in a sealed bag.
Noticeable
Different brands and models of underwater camera housings are usually equipped with O-rings of different specifications. For example, the Olympus PT-054 and PT-059 underwater camera housings use different O-rings models, which need to be replaced according to the specific model. In addition, high-end underwater camera housings may use a double O-ring design to further reduce the risk of water leakage.
