Product review (5 stars): Great replacement gasket for a Bosch Nexxt 300 front load washer.
If you search on youtube, you will find some videos of someone installing one of these gaskets.  My washer is a Bosch Nexxt 300, and the door gasket cracked after years of use.  There are some tight spots to work in, but if you lubricate the large ring/spring that comes with this gasket, you can do the installation in about 30 to 45 minutes.  This gasket seems to be made as well as the original one.
