hey definitly buddy! I remember going through the same thing! I eventually found a rubber grommet at a hardware store and took some Vitamin E oil and......... trust me........... it was a real bitch, i didnt even think it was going to work after a while, but i got that thing in........... i cant remember if i used two one on each side. i think i did use two. then slid my tap through the grommet. it was a super tight fit. but the rubber was food grade and there arent really any sealants that are food grade. a guy at a specialty sealant store told me that it was common in the industry to tell people or companies even that certain ones were food grade when they werent. he also told me that he wouldnt trust one that claimed to be food grade. he even had food grade ones for sale, but they were quite expensive. it was hard to garner information on this, but this guy sounded like he was a real expert in the field.
