Used twice, filters incredibly well. This is the one specific to Blichmann kettles. If you have a different kettle you will need a compression fitting.
Would the old fitting need to be cut off, or could you just trade out one fitting for another?
Still for sale.
This has no fitting. It's meant to replace the blichmann dip tube. To use with another kettle simply add a compression fitting.
