Yes, use what fits. I've ordered from different manufacturers, and it seems like each has a different thickness. I like aluminum ones because they seal better under less torque. The copper can be reused if you're into annealing. Really, aluminum washers are used for most things, so copper is really intended for higher torque settings.A bit of naff-naff and trivia but - can anybody clarify the oil banjo union washer size? A standard M14 copper washer is 1.50 mm in thickness. The below dimension from the repair manual is 1.22 mm thick - not standard dimensions.
An error? I guess most are just using standard M14 copper washers? Or crush washers?
Thanks.
