Performance Of Elastomeric Components In Contact With Potable Water

Synopsis

For years the use of rubber gaskets, valves, hydrants, and fitting have been successfully widely used. However, recently an increase of elastomer failures has been noted. While the degradation appears to be coincident with a disinfectant change from chlorine to chloramines, other factors including temperature and pH and are believed to play roles. This research initiative was intended to clarify the factors that contribute to elastomer degradation and provide a quantitative method for predicting the performance and life expectancy of in-service elastomer components.
