oil change; crush washer found, what do you use for the sealing ring, crush washer. Options

[rmdinmd]

as the description says where can you get them and what do you use. you buy the oil screen filter kit and it comes with the two gaskets and one crush ring not two.

for now I am using a neoprene washer as a gasket, I think I have read where some guys use copper washers. is that correct and if so size and where to get would be very helpful. I am trying hard to do things right to the point I bought a torque wrench that goes down to 5 lbs so I could avoid over torqueing the strainer nut.

thanks in advance

These are available from AA at a $1.00 each the size is 22x27mm, of course you have the minimum shipping issue... You might be able to get a bunch at a place like this for the same shipping or less and probably less per piece in a larger quantity: http://www.mcmaster.com/# Sometimes I'll do a Google search with just the part # to see what options pop up too.
