Asc 318908480 Black Cast Iron Hex Bushing 3 in X 0.5 in

Product Description

The ASC Engineered Solutions 318908480 is a black cast iron hex bushing designed to reduce pipe connections from a 3-inch female thread to a 0.5-inch male thread. The hex body provides a wrench flat for secure installation and proper torque application. Weighing 1.56 pounds, this domestically produced fitting is built for heavy-duty service in gas, steam, and water piping systems. It is suited for use by licensed plumbers and pipefitters working on commercial or industrial piping assemblies where durable, threaded iron fittings are required.

This hex bushing is used in applications where a straight reduction is needed between threaded iron pipe segments. The cast iron construction and black coating make it appropriate for dry or low-moisture environments including gas distribution lines, steam headers, and industrial water supply runs. It is commonly installed in mechanical rooms, plant piping, and commercial HVAC or plumbing systems requiring NPT threaded connections at the specified reduction size.

Key Features

• 3-inch female NPT to 0.5-inch male NPT straight reduction
• Cast iron construction for strength in high-pressure and high-temperature piping service
• Black coating finish suitable for gas and steam line applications
• Hex body design allows wrench engagement for leak-free makeup
• Domestically produced fitting meeting standard pipe fitting quality expectations

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard NPT threaded black iron pipe systems requiring a 3-inch to 0.5-inch reduction.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and IFGC or IPC requirements. Shut off and depressurize the piping system before threading in the bushing. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Do not over-tighten; use a pipe wrench on the hex flats to achieve a proper, leak-free connection without cracking the fitting.
