I need a oil seal to suit the lid of a Fram oil filter (orange) , any leads would be helpfull, Thanks.

pic might help identify what your after....depending on what shape the seal is a company like NORSEAL can usually help

from memory its only an O ring isnt it ??

It is the large round oil seal that goes under the lid when you screw it down. Approx 150mm diameter

is it flat or round do u have a pic
