When you buy a gasket for a fridge or freezer, from a place like
ApplianceParts.com, or any of the others, how old is it?

I need a new thermostat for my 31-year old Sears fridge, so while I'm
at it, I thought I'd buy a door gasket and maybe a freezer one (Have
to go downstairs and check its condition).

Will it also be 31 years old? 20? 10? 5?

Do they make them in batches according to what they sell, so it might
be only as old as the last one they sold? How many different sizes do
doors come in?

For the one I've looked at so far, the picture shows it with four
finished corners.

Or should I but a universal gaskets which will be practically new, but
I have to cut out the V sections (which I could conceivably screw up)?
And I guess the corners will never be "welded" like one made
specifically for my door.




BTW, I think it interesting that several of these webpages show the
same parts with the same pictures in the same order, and the same
number of total parts for my model, 261. They must be all one company,
or they all buy the software and esp. the data from the same supplier.

P.S. Please don't try to talk me into buying a new refrigerator. This
one seems to be made of steel. It shows no sign of wearing out, and
may outlast a new one bought today.
