I'm thinking an aluminum frame with a rabbet on the inside to trap and slightly compress an elastomer seal. O-Ring cord stock is available in a square cross section so that would be my first choice if I could find something in a lower durometer that is oil resistant. There are also Buna-N foams available in strip form that might be good candidates.
