Bulkhead Tank Fitting: Polypropylene Body, 2 in Female Threaded Inside Connection

These through-wall fittings are constructed of polypropylene which provides a moisture barrier and is resistant to chemicals and abrasion. They install through the wall of the tank, drum, or fluid container by inserting the shaft through the hole of the tank from the inside so that the shaft is sticking out of the tank. A gasket seals the internal fitting as a nut is threaded onto the exposed shaft to secure it to the tank.
