Pelican Replacement "O" Ring for the 1490 Cases

If you're an underwater photography enthusiast, ensuring the watertight integrity of your equipment is paramount, and the Pelican Replacement "O" Ring for the 1490 Cases is an essential component in maintaining that seal. O-rings are critical to the functionality of your underwater camera system, as they provide the necessary barrier against water ingress. It's advisable to always have spare O-rings in your camera case to prevent any unexpected failures. The effectiveness of an O-ring largely depends on its condition. A well-lubricated O-ring is elastic and can conform uniformly around its channel, ensuring a tight seal.

In contrast, a dry O-ring creates excessive friction, preventing it from reshaping properly and compromising its ability to prevent flooding. Therefore, it's crucial to inspect the O-ring every time you open your camera to change film or access the interior. Regular cleaning and lubrication after each day of diving are recommended to maintain optimal performance. When assessing the sealing capability of an O-ring, err on the side of caution. If there's any doubt, it's best to discard and replace it. Remember, never use sharp or pointed objects to remove an O-ring, as this can damage it.

Instead, utilize an O-ring remover tool for safe extraction. Additionally, avoid over-greasing, as excessive grease can attract debris, disrupting the seal and leading to potential flooding. Silicone grease serves as a protective layer against abrasion but is not a sealant. A properly greased O-ring should appear moist and shiny, indicating it's ready to provide reliable protection for your underwater adventures.
