Asc Engineered Solutions 318908969 Cast Iron Hex Bushing

Product Description

The ASC Engineered Solutions 318908969 is a black cast iron hex bushing designed to reduce pipe thread connections from a 4-inch female fitting down to a 1-1/4-inch male thread. Cast iron construction delivers the durability required in demanding plumbing and mechanical piping systems. The hex profile allows for wrench engagement during installation, ensuring a secure, leak-resistant connection. Weighing 3.54 pounds, this domestically produced bushing is built to the dimensional standards expected in professional pipe system assemblies. Plumbers and pipefitters working on gas, water, or industrial piping systems will find this fitting suitable for common reducing applications.

This hex bushing is used in residential and commercial plumbing systems where a large-diameter pipe run must transition to a smaller branch or fixture connection. Typical applications include drain, waste, and vent piping as well as low-pressure gas distribution lines where cast iron fittings are specified. The black coating is standard for gas line applications and provides surface protection during service. Licensed plumbers and pipefitters are the primary installers of this type of fitting in mechanical piping systems.

Key Features

• 4-inch female thread to 1-1/4-inch male thread reduction

Compatibility

Designed as an OEM-style replacement or direct installation fitting for 4-inch to 1-1/4-inch threaded pipe connections in cast iron piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing and mechanical codes. Shut off and depressurize the piping system before removing or installing any threaded fittings. Apply appropriate thread sealant or tape to the male threads before assembly. Do not over-torque cast iron fittings, as the material is brittle and susceptible to cracking under excessive force.
