Pro Tip
The nut that tightens this V-clamp is a separate component confirm whether yours is damaged or missing before ordering, as you may need both pieces. When reassembling the filter housing, inspect the tank O-ring at the same seam; replacing a worn O-ring at the same time prevents a return trip once the filter is back in service. Match the WC19-43 part number against the label on your existing clamp or your filter’s parts diagram before ordering.
