Asc 310066808 3/4 in Black Malleable 45 Y Branch

Product Description

The ASC Engineered Solutions 310066808 is a 3/4 inch black malleable iron lateral 45-degree Y branch fitting used to split or combine pipe flow at a 45-degree angle in threaded pipe systems. This type of fitting is a standard component in low-pressure gas, steam, and water distribution piping where a branch takeoff is needed without the abrupt direction change of a standard tee. Its black malleable iron construction provides strength and ductility suitable for threaded assembly. Licensed plumbers and pipefitters install this fitting during new construction and retrofit work on commercial and residential pipe runs.

This lateral Y branch is suited for use in threaded black iron pipe systems commonly found in natural gas distribution, compressed air lines, and low-pressure steam or hydronic systems. The 45-degree lateral angle reduces turbulence at the branch point compared to a standard 90-degree tee configuration, making it a practical choice in flow-sensitive installations. It is appropriate for both above-ground and in-wall installations where code-compliant threaded connections are required.

Key Features

• Malleable iron construction provides durability and resistance to impact and vibration
• Black finish is standard for gas piping applications
• 45-degree lateral branch angle reduces turbulence and flow resistance at the junction
• 3/4 inch fitting size is a common trade size in residential and light commercial pipe systems
• Threaded connections compatible with standard NPT pipe threads

Compatibility

Designed as an OEM-style replacement or standard-stock fitting for 3/4 inch threaded black iron pipe systems in gas, steam, and water service applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, IFGC requirements for gas piping, or IPC requirements for water and steam service. Shut off and depressurize the line completely before disassembly or fitting installation. Apply an approved pipe thread sealant or PTFE tape rated for the service medium to all male threads before assembly. Do not over-torque threaded connections in malleable iron fittings, as cracking can occur.
