Asc 8700121455 Reducing Malleable Black Iron Tee 3/4x1/2x3/4

Product Description

The ASC ENGINEERED SOLUTIONS 8700121455 is a reducing malleable black iron tee designed for threaded pipe assemblies in plumbing, mechanical, and gas distribution systems. The fitting connects a 3/4-inch run (A side) to a 3/4-inch run (B side) with a 1/2-inch outlet (C middle), allowing a branch takeoff at a reduced port size. Flat-banded construction adds strength at the shoulder. Manufactured from malleable iron to ASTM A-197 chemical and physical property standards, this fitting handles the stresses of threaded assembly without cracking. Licensed plumbers and pipefitters are the typical installers in commercial and residential applications.

This tee is suited for use in low-pressure steam, water, gas, and air piping systems where a branch reduction is required. The 3/4-inch by 1/2-inch by 3/4-inch configuration is a common size for domestic water distribution and gas supply branch lines. It conforms to Federal Specification WW-P-521F, ANSI B-16.3 for dimensions, and ANSI B-2.1 for pipe threads, making it appropriate for use on any system requiring standard NPT-threaded black iron fittings. The flat-banded style is the traditional malleable iron fitting form found throughout commercial and residential piping installations.

Key Features

• Malleable iron construction per ASTM A-197 for strength and impact resistance
• Flat-banded profile — standard configuration for threaded black iron systems
• NPT threads per ANSI B-2.1 for compatibility with standard pipe and fittings
• Dimensions per ANSI B-16.3 ensuring consistent fit in threaded assemblies
• 3/4 In. x 1/2 In. x 3/4 In. reducing configuration — run, outlet, run sequence
• Meets Federal Specification WW-P-521F

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard NPT-threaded black iron pipe systems requiring a reducing tee in the 3/4-inch by 1/2-inch by 3/4-inch size configuration.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the International Plumbing Code or International Fuel Gas Code where required. Shut off and depressurize the affected pipe section before disassembly or installation. Apply an appropriate thread sealant or PTFE tape to all male threads before assembly, and tighten to a firm, leak-free engagement without over-torquing the fitting. Do not use this fitting on systems or pressures beyond the rated capacity of standard malleable iron black fittings per ANSI B-16.3.
