The Pentek PFW190 is a 1/2 Circle Water Filter Housing Wrench. This housing wrench has a 3-5/8" C-style opening that assists the user in untightening the housing sump from their manifold or housing head. The PFW190 is designed to work with most standard and slimeline water filter housings. Please do not use this wrench to tighten the housing, because overtightening may cause enough damage that leaking may be an issue.It is best practice to only hand tighten the housing when maintenance is complete.

NOTE: This wrench will assist in removing 10" and 20" Standard Filter Housings (5" Diameters)
