Asc Engineered Solutions 8700124251 Malleable Iron 90 Deg Elbow 1 in

Product Description

The ASC Engineered Solutions 8700124251 is a 1-inch malleable iron 90-degree elbow, also known as a quarter bend, designed for threaded pipe systems in commercial and industrial plumbing, mechanical, and HVAC piping installations. Constructed from malleable iron to ASTM A-197 chemical and physical property standards, this flat-banded fitting delivers reliable directional change in low-pressure pipe runs. Threads conform to ANSI B-2.1 and overall dimensions meet ANSI B-16.3, ensuring compatibility with standard NPT threaded pipe and fittings. Licensed plumbers and pipefitters are the typical installers on both new construction and retrofit work.

This fitting is suited for residential and light commercial plumbing, hydronic heating, fire protection support piping, and general mechanical systems where a 90-degree direction change in a 1-inch threaded pipe run is required. The flat banded style is a widely accepted standard configuration used across a broad range of piping applications. It meets Federal Specification WW-P-521F, making it appropriate for federally specified construction projects and government facility work.

Key Features

• Malleable iron construction per ASTM A-197 for strength and ductility in threaded piping systems
• Flat banded design conforming to standard malleable iron fitting profile
• 1-inch pipe size providing a full 90-degree directional change in threaded pipe runs
• Threads machined to ANSI B-2.1 for proper NPT thread engagement
• Dimensions per ANSI B-16.3 ensuring drop-in fit with standard malleable iron fittings
• Meets Federal Specification WW-P-521F for use on government and federally specified projects

Compatibility

Designed as an OEM-style replacement and standard-use fitting for 1-inch NPT threaded malleable iron piping systems in plumbing, mechanical, and HVAC applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or local mechanical codes. Shut off and depressurize the pipe system completely before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to male threads before assembly, and hand-tighten before using a pipe wrench to seat the fitting. Do not over-tighten malleable iron fittings, as the material can crack under excessive torque.
