Thru-Hull 3/4", Mushroom, Threaded Bronze

Part #: Z5242
$38.39

This National Pipe Straight Mechanical threaded mushroom style thru-hull. Usually we would recommend the Marlon thru-hull due to its strength and corrosion resistance, but its length is limited. This bronze 3/4" thru-hull is used in situations where an extra length is required in the hull. Locations include sink drain and head intake in a wide variety of boats, from the Catalina 22 to the Catalina 42.
