Good quality
If you have one of their all home filters, you need a spare ready when you change out the filter, some times it will last 2 or even 3 changes, other times change it with every filter change, as the saying goes “it’s better to have it and not need it as it is to need it and not have it”

Perfect fit
It stopped the leak by fitting perfectly. Great value for such a necessary part. It is still holding up after 2 weeks use. I would definitely order again.
