90* oil filter adapter????

i had one years ago that the copper washer was hard as balls on. i chased my *** for a good hot minute on it. wound up torching the washer to get some soft back into it and lightly dressing under the bolt head and boss with some sandpaper.

to my knowledge these are NLA, so used is the only option.

brand new copper washer but it could be too hard.. wonder if i should try heating that damn thing.. wonder if they are made to hard.. now that you mention it i do remember re-using an old copper washer on the old engine and my buddy heated it up and that ***** never leaked.
