I need the part number for a gasket for a delfield SMR1-S3.
Perhaps you should contact PartTOWN:
That's because there are so many different ones. You'll have to call with serial number for that. Recommend that you also measure the outside of the gasket to verify it's correct.
What you have is a spec line, aluminum box stainless front, solid single door reach in refrigerator. Problem is they list it under the SSR1, which is full stainless.
Note the different profiles of gaskets and minor dimension differences. here.
