Could someone please recommend a polymer to be over-molded onto a metal surface to create a soft seat valve? This valve will be used in LPG applications. We are currently using Buna-N and it appears that the liquid has gotten between the metal and the rubber and caused the rubber to balloon up.Thank you!
