SEA WATER Resistant O-Rings and Seals

Sea water is a combination of salt water and freshwater, which is a naturally occurring solution of minerals, salts and other elements. Common names for sea water include seawater, ocean water, brine and saline water. The common uses for sea water include industrial water treatment, agricultural irrigation, fish farming, desalination, and environmental protection.

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.
