Asc Engineered Solutions 8700121653 Black Iron Reducing Tee

Product Description

The ASC Engineered Solutions 8700121653 is a reducing malleable black iron tee designed for threaded pipe assemblies in gas, air, and low-pressure fluid distribution systems. The fitting connects a 1-inch run on both the A and B sides to a 1/2-inch outlet on the C middle port, following the standard A-B-C sizing sequence for reducing tees. It is constructed from malleable iron with a flat banded exterior finish. Licensed plumbers, pipefitters, and gas technicians typically install this fitting in commercial and residential piping applications where a branch reduction is required at a tee junction.

This fitting is suited for threaded black iron piping systems in residential and light commercial installations, including natural gas distribution, compressed air lines, and steam or water piping operating within standard pressure ranges. The reducing configuration allows a main run to continue at full size while stepping down the branch outlet to 1/2 inch, a common arrangement in gas supply manifolds and HVAC piping drops. Installation follows standard NPT thread engagement practices.

Key Features

• Malleable iron construction meets ASTM A-197 chemical and physical property requirements
• Flat banded exterior profile for easy wrench engagement
• Threads conform to ANSI B-2.1 for standard NPT pipe thread fit
• Dimensions comply with ANSI B-16.3 malleable iron fitting standard
• Meets Federal Specification WW-P-521F
• Reducing outlet allows 1-inch main run with 1/2-inch branch takeoff in a single fitting

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard NPT threaded black iron pipe systems in gas, air, steam, and water service applications.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or gas technician in accordance with applicable local codes, the International Fuel Gas Code (IFGC), or the International Plumbing Code (IPC). Shut off and depressurize the line before disassembly or fitting installation. Apply an approved thread sealant or PTFE tape rated for the intended service medium to all male threads before assembly. Do not over-tighten; use a backup wrench on adjacent fittings to avoid stressing upstream connections.
