Has O-ring type seal...this is a factory oil filter. Remember to burp the engine or oil will not flow thru the filter and your oil light will stay on. To burp it..just start it for a few seconds after oil change is complete..shut it off...then unscrew the filter until oil comes out..then re-tighten. When you restart the bike the oil light will go right out...Would buy again.
