Proper maintenance of your O-rings is vital for optimal performance. Lubricated O-rings are elastic and can uniformly shape themselves around the channel, providing a secure seal. In contrast, dry O-rings create excessive friction, preventing them from reshaping properly and compromising the seal, which could lead to flooding. Therefore, it is important to inspect the O-ring every time you open the camera to change film and service it if necessary. After each diving day, make sure to clean and lubricate the O-rings to maintain their effectiveness.
When in doubt about an O-ring's sealing capability, it is best to discard and replace it to ensure the safety of your equipment. Always use an O-ring remover tool to avoid damaging the O-ring with sharp or pointed objects. Be cautious not to overgrease, as excessive grease can attract debris, disrupting the seal and increasing the risk of flooding. Remember, silicone grease is not a sealant but a protective layer against abrasion. A properly greased O-ring should appear moist and shiny, indicating it is ready to provide a reliable seal for your underwater photography needs.
