This sounds like a site specific issue. Not likely that it's a product issue. My first thought was the lube used at installation. Most common elastomer used is EPDM which does not play well with hydrocarbons. Usually see some swelling initially not sure what happens long term.
Trust the manufacture send them a sample, they see it all. They want to know what happened to their product most likely more than you do.
