Asc Engineered Solutions 8700121208 Black Iron Tee

Product Description

The ASC Engineered Solutions 8700121208 is a reducing malleable black iron tee fitting used in threaded pipe systems for gas, steam, and liquid service. It features a 1/2-inch A-side run, 1/2-inch B-side run, and 3/8-inch C-middle outlet, following the standard A-B-C sizing sequence. The flat-banded malleable iron construction provides the ductility and strength required for mechanical and plumbing applications where vibration or stress could affect rigid cast iron. Licensed plumbers and pipefitters install this type of fitting in branch connections on black iron pipe systems. Compliance with Federal Specification WW-P-521F, ANSI B-16.3, ANSI B-2.1, and ASTM A-197 confirms dimensional accuracy and material integrity.

This reducing tee is suited for residential and light commercial black iron pipe installations, including gas distribution piping, steam heating systems, and general fluid service lines. The 3/8-inch branch outlet allows a reduction in line size at the tee point without requiring additional bushings. It is sold individually and is appropriate for any threaded pipe application where a branch takeoff at a reduced outlet size is needed. Installers working with Schedule 40 black iron pipe will find this fitting compatible with standard NPT thread engagement requirements per ANSI B-2.1.

Key Features

• Reducing configuration: 1/2-inch run x 1/2-inch run x 3/8-inch branch outlet
• Malleable iron construction per ASTM A-197 for ductility and impact resistance
• Flat-banded design for consistent wall thickness and mechanical strength
• NPT threads per ANSI B-2.1 for standard pipe thread compatibility
• Dimensions conform to ANSI B-16.3
• Meets Federal Specification WW-P-521F for pipe fittings

Compatibility

Designed as an OEM-style replacement or new-installation fitting for threaded black iron pipe systems using standard NPT connections on 1/2-inch and 3/8-inch Schedule 40 pipe.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with local plumbing codes and IFGC requirements where gas service is involved. De-pressurize and isolate the pipe section before disassembling or threading any fitting. Apply a listed pipe thread sealant or PTFE tape rated for the service medium to all male NPT threads before assembly. Do not over-tighten; hand-tighten first, then use a pipe wrench for final engagement without exceeding thread limits.
