When rubber is exposed to sea water, it can cause a variety of failures. The most common type of failure is chemical degradation caused by the salt in the water which can cause the rubber to become brittle and crack. Additionally, the salt water can lead to accelerated oxidation which can cause the rubber to weaken and break down. Other failures that can occur include swelling, loss of elasticity and discoloration.
