Anvil 2" Malleable Iron Hex Locknut

The Anvil 0318913647 is a 2-inch hex locknut machined from malleable iron for plumbing drain systems. It connects via FNPT threads and conforms to ASME B 16.3 standards. The fitting carries a Class 150 rating and is UL and FM approved for drain component applications.

For drain lines needing a 2" iron locknut

This locknut suits installers assembling 2-inch malleable iron drain piping to Class 150 specifications. It is not for pressure service, so systems carrying pressurised water, steam or gas must use rated pressure fittings instead. Buyers needing a different pipe diameter or a pressure-rated union should select another component.

2-inch FNPT malleable iron construction

The single specification that determines fit is the 2-inch FNPT thread size combined with the malleable iron material and Class 150 rating. The hex measures 2 7/8 inches across flats for wrench engagement. Verify that the mating pipe and system design match these exact parameters before installation.
