Anvil 310055207 Black Malleable Iron Reducing Tee Class 150

Product Description

The ANVIL 310055207 is a black malleable iron reducing tee rated Class 150 and manufactured to ASME B16.3 standards. It features a 3 inch by 3 inch run with a 1 inch branch outlet, making it suitable for reducing branch connections in low-pressure piping systems. The fitting is 100 percent gas tested at a minimum of 100 psi at the factory, confirming pressure integrity before it leaves the line. Licensed plumbers, pipefitters, and mechanical contractors install this fitting in gas, steam, air, and water distribution systems where a durable threaded iron connection is required.

This reducing tee is used in residential and commercial piping applications where a branch line of smaller diameter must be taken off a main run. Typical installations include gas distribution piping, compressed air headers, hydronic heating systems, and general industrial process piping. The black finish is standard for gas service. The NPT-threaded ends allow connection to standard pipe and fittings without special tooling.

Key Features

• Manufactured to ASME B16.3 for Class 150 malleable iron fittings
• 100 percent factory gas tested at a minimum of 100 psi
• 3 inch by 3 inch run with 1 inch reducing branch outlet
• Black malleable iron construction for gas and general piping service
• NPT-threaded ends for standard pipe compatibility

Compatibility

Designed as an OEM-style Class 150 malleable iron fitting for use with standard NPT-threaded black iron pipe in residential and commercial gas, steam, air, and water piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and fuel gas codes, including IFGC and IPC references where required. Shut off and depressurize the line completely before disassembling or installing any threaded fitting. Apply an approved pipe thread sealant or PTFE tape rated for the intended service medium to all male threads before assembly. Do not overtighten NPT connections, as malleable iron fittings can crack under excessive torque.
