This Sea & Sea o-ring Set is for the Sea & Sea housings for the Canon Digital Rebel XT (350D), Nikon D50 and D200 cameras. The set includes the body o-ring for these housings. The o-ring resembling a thick rubber band is designed to establish a watertight seal when going underwater.
Manufactured to precision tolerances required to hold a pressure seal on your housing and made of elastomeric material, it provides the means by which a watertight seal is formed.
