Asc 8700120309 Malleable Black Iron Tee 1/8 Inch

Product Description

The ASC Engineered Solutions 8700120309 is a 1/8 inch malleable black iron tee designed for threaded pipe assemblies in gas, steam, and water distribution systems. Built to flat-banded standard malleable iron construction, this fitting meets Federal Specification WW-P-521F, ANSI B-16.3 for dimensions, ANSI B-2.1 for pipe threads, and ASTM A-197 for chemical and physical properties. At 0.091 pounds, it is a lightweight but durable component suited for tight-space branch connections. Plumbers, pipefitters, and mechanical contractors install this fitting where a 1/8 inch threaded branch connection is required on low-pressure piping runs.

This tee is used in residential and light commercial piping systems where black iron threaded fittings are standard practice. Typical applications include gas distribution headers, steam piping, and low-pressure air or water lines. The 1/8 inch size is common in pilot gas lines, instrumentation taps, and small-diameter branch connections on larger assemblies. It is sold individually and is compatible with standard NPT-threaded pipe in the corresponding size.

Key Features

• Malleable iron construction meets ASTM A-197 chemical and physical property requirements
• Flat-banded tee body conforms to ANSI B-16.3 dimensional standards
• ANSI B-2.1 compliant NPT pipe threads for leak-resistant assembly
• Meets Federal Specification WW-P-521F for standard malleable iron fittings
• Lightweight at 0.091 pounds, suitable for compact installation spaces

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard 1/8 inch NPT threaded black iron piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC). Shut off and depressurize the line before disassembly or installation. Apply an appropriate pipe thread sealant or tape rated for the intended service medium. Do not over-tighten threaded connections, as malleable iron fittings can crack under excessive torque.
