Asc 8700128906 Hex Bushing Black Iron 3/8 X 1/4 in

Product Description

The ASC Engineered Solutions 8700128906 is a malleable black iron hex bushing used to reduce pipe thread sizes in low-pressure piping systems. The male thread measures 3/8 inch and the female thread measures 1/4 inch, making it a standard reducing bushing for gas, air, water, and steam service lines. The hexagonal body provides a wrench flat for torque application during assembly. At 0.028 pounds, it is a compact fitting suited for tight runs where a coupling-and-nipple reduction would add unnecessary bulk. Licensed plumbers, pipefitters, and HVAC technicians install this fitting as part of threaded pipe assemblies in both new construction and maintenance work.

This bushing is used in residential and light commercial piping systems where a threaded pipe or valve port must be reduced from 3/8 inch to 1/4 inch NPT. Common applications include gas appliance supply lines, compressed air distribution headers, steam systems, and water service connections. The malleable iron construction handles moderate pressure and vibration better than cast iron, making it appropriate for mechanical rooms and utility installations where fittings may be subject to minor movement or thermal cycling.

Key Features

• Malleable black iron construction for durability in gas, air, steam, and water service
• 3/8 inch male NPT x 1/4 inch female NPT reducing configuration
• Hexagonal body design allows standard wrench engagement for secure make-up
• Meets Fed. Spec. WW-P-471-B for ferrous plugs, bushings, and locknuts
• Dimensioned to ANSI B-16.14 with threads conforming to ANSI B-2.1

Compatibility

Designed as an OEM-style replacement or standard-stock fitting compatible with 3/8 inch male NPT to 1/4 inch female NPT threaded pipe systems in malleable iron fitting assemblies.

Installation Notes

This fitting is installed by licensed plumbers or pipefitters working on threaded iron piping systems. Shut off and depressurize the line before disassembly or installation. Apply an approved thread sealant or PTFE tape to male threads before assembly and tighten with a pipe wrench to achieve a leak-free joint without over-stressing the fitting. For gas service, verify all connections with an approved leak detection method before restoring pressure, in accordance with applicable codes including IFGC and local authority requirements.
