Mars 69029134701 1/4 in Malleable Iron Street Elbow 150 Lb

Product Description

The MARS 69029134701 is a 90-degree street elbow fitting manufactured from malleable iron with a black oxide finish. Rated at 150 lb pressure class and 300 psi working pressure, this fitting is built to handle demanding pipe distribution applications. The 1/4 in nominal size uses a male NPT inlet and female NPT outlet configuration, making it a true street elbow that connects directly into another fitting without a nipple between. The SCH 40/STD schedule rating and domestic manufacture make this a dependable choice for licensed tradespeople working on residential and light commercial piping systems.

This street elbow is suited for gas, water, and air distribution lines where a compact 90-degree directional change is needed. The MNPT x FNPT end style allows the male end to thread directly into a tee, coupling, or valve, saving space in tight installations. Typical applications include natural gas branch lines, compressed air distribution headers, and general-purpose black iron pipe systems commonly found in mechanical rooms, boiler rooms, and utility spaces. The temperature rating of -20 to 150 degrees F covers standard indoor and outdoor service conditions.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and IFGC or IPC requirements. Shut off and depressurize the supply line before removing or installing any pipe fitting. Apply an appropriate pipe thread sealant or PTFE tape to the male threads before assembly. Do not over-torque malleable iron fittings, as the material can crack under excessive force.
