Asc 8700121307 3/4x3/4x1/2 Reducing Black Iron Tee

Product Description

The ASC Engineered Solutions 8700121307 is a reducing malleable black iron tee designed for threaded pipe assemblies in gas, steam, and water distribution systems. Sized at 3/4 inch x 3/4 inch x 1/2 inch (A side x B side x C middle), this flat-banded fitting provides a reliable threaded connection at each port. Malleable iron construction meets ASTM A-197 chemical and physical property requirements. The fitting conforms to ANSI B-16.3 dimensional standards and ANSI B-2.1 pipe thread specifications, making it a code-compliant choice for commercial and industrial piping work. Licensed plumbers, pipefitters, and mechanical contractors are the primary installers.

This reducing tee is suited for residential and commercial piping installations where a branch line steps down from a 3/4-inch run to a 1/2-inch outlet. Typical applications include hydronic heating systems, natural gas distribution piping, steam lines, and general plumbing rough-in work. The flat-banded body style is standard for black iron threaded fittings used throughout mechanical rooms, utility spaces, and above-ceiling pipe runs. Sold individually.

Key Features

• Malleable iron construction per ASTM A-197 for reliable mechanical strength in threaded systems
• Flat-banded body style standard for black iron threaded fittings
• Conforms to ANSI B-16.3 dimensional standards for consistent fit with standard pipe and fittings
• ANSI B-2.1 compliant pipe threads for leak-resistant engagement
• Meets Federal Specification WW-P-521F
• Reducing outlet allows transition from 3/4-inch run to 1/2-inch branch in a single fitting

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard threaded black iron pipe systems using NPT connections in 3/4-inch and 1/2-inch pipe sizes.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes, including IPC and IFGC requirements where applicable. Shut off and depressurize the pipe system fully before disassembling or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to all male NPT threads before assembly. Do not over-tighten; use a pipe wrench with a backup wrench on adjacent fittings to avoid stress on connected piping.
