The Importance of Elastomer Consistency in PVC Pipe Gaskets

PVC pipe systems rely on more than pipe design and installation practices to perform reliably. The long-term success of Sewer, IPS, and C900/C905 applications depends heavily on one critical component: the rubber gasket—and more specifically, the consistency of its elastomer properties.
​
When elastomer formulations vary, gasket performance becomes unpredictable. Even small changes in hardness, elasticity, or compression behavior can compromise a seal, increasing the risk of leaks or premature failure.
