Asc Engineered Solutions 8700127403 Black Iron Street Elbow

Product Description

The ASC Engineered Solutions 8700127403 is a 1-inch 90-degree street malleable black iron elbow, also known as a 1/4 bend street elbow. It features one male NPT end and one female NPT end, allowing it to change pipe direction 90 degrees without requiring an additional coupling or nipple. This fitting is manufactured from malleable iron and meets Federal Specification WW-P-521F, ANSI B-16.3 dimensional standards, ANSI B-2.1 pipe thread standards, and ASTM A-197 chemical and physical property requirements. Licensed plumbers and pipefitters install this type of fitting in black iron piping systems for gas, compressed air, and similar applications.

This street elbow is suited for use in residential and light commercial piping installations where a compact 90-degree directional change is needed. The male-by-female NPT configuration allows it to thread directly into a tee, fitting, or valve outlet without an extra nipple, saving space in tight installations. It is sold individually and is appropriate for new construction, retrofit, and repair work on black iron pipe systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and IFGC requirements for gas piping applications. Shut off and depressurize the pipe system completely before disassembling any fittings. Apply an appropriate thread sealant or pipe thread tape rated for the service medium before threading connections. Do not overtighten NPT connections, as malleable iron fittings can crack under excessive torque.
