Sea and Sea Extension Rings

Find Sea and Sea extension rings for compatible camera housings, ports and lenses.

Check camera, lens and housing compatibility

Use the manufacturer's port chart for the exact housing and lens combination. Extension length and port fitting must match the complete setup; a ring should not be selected by diameter alone. Check required seals and any additional components specified for that configuration.
