Re: Polyethylene Washers ?????

I have never heard of washer specifically made from polyethylene.  Perhaps
you could get a flat sheet and have them cut out of it.  If you only need a
few, you can easily cut them yourself.  If you need a large number, perhaps
the laser cutting place could easily zap them out for you.

Cheers,
