Anvil 0318906369 Black Hex Bushing 3/4 X 1/2 in 150 Psi

Product Description

The ANVIL 0318906369 is a black malleable iron hex bushing rated for Class 150 service in threaded pipe systems. It steps down a 3/4-inch female thread to a 1/2-inch male thread and carries a pressure rating of 150 psi for both liquid and steam applications. The black finish is standard for malleable iron fittings used in gas, air, and steam distribution. Plumbers, pipefitters, and mechanical contractors install this fitting when reducing pipe size within a threaded black iron system. At 0.09 pounds, it is a compact, single-piece reducer with no gaskets or seals required.

This hex bushing is suited for residential and light commercial piping installations where Class 150 malleable iron fittings are specified. Typical applications include natural gas supply lines, compressed air distribution, steam heating systems, and water service piping. The thread-by-thread end connection allows direct wrench installation into standard NPT-threaded fittings, valves, and equipment ports without additional adapters.

Installation Notes

Installation is performed by a licensed plumber or pipefitter following applicable code requirements, including IFGC for gas piping. Shut off and depressurize the supply line before installing or removing any threaded fitting. Apply an approved pipe thread sealant or PTFE tape to the male threads before assembly. Use a pipe wrench on the hex body to tighten — do not use the connected pipe as leverage.
