Product review (4 stars): It is what it is ...
I ordered the part because the original in my dishwasher was a two piece, and the ends that joined were chewed up.  The price here was better than I had found elsewhere, and it seemed to be of decent quality.

Since we're not talking about the o-ring on a space shuttle engine here, it suffices to say that the tube has met my expectations. My one piddling gripe is that it didn't come with a replacement screw for mounting it and the existing one stripped due to rust, but again it's a minor issue.  I'd definitely recommend it to others who needed a similar part.
