Great Replacement housing

This worked great as a replacement housing for my TFC Membrane on my Kent Marine HS-35 system. The only difference is that the membrane doesn't sit as far in as in the original housing (specs on original say 3/4" and this one only allows the membrane to be 1/2" in). However, so far it hasn't made any difference in performance that is noticeable. As all ways from Marine Depot the shipping was fast and cost was reasonable.
