Asc Engineered Solutions 1B.BML 90 Degree Elbow 1-1/4 in

Product Description

The ASC Engineered Solutions 1B.BML is a 90-degree pipe elbow designed for use in threaded piping systems across plumbing, gas, and mechanical applications. Manufactured from malleable iron with a black finish, this fitting accepts 1-1/4 inch female NPT connections on both ends and is rated for 150 lb service. The malleable iron construction provides the toughness needed to handle vibration and mechanical stress in working pipe systems. Licensed plumbers and pipefitters rely on this class of fitting for its consistent thread engagement and dimensional conformance to standard ANSI/ASME specifications for threaded fittings.

This elbow is suited for residential and light commercial piping installations where a 90-degree direction change is required. Typical applications include natural gas distribution lines, steam systems, compressed air, and water supply piping. The black finish is standard for gas piping applications and is commonly specified by mechanical contractors and plumbing professionals in both new construction and retrofit work.

Key Features

• 90-degree elbow geometry for right-angle pipe routing
• 1-1/4 inch FNPT connections on both ends for standard threaded pipe
• 150 lb pressure class malleable iron construction

Compatibility

Designed as an OEM-style threaded fitting compatible with standard 1-1/4 inch NPT pipe in 150 lb malleable iron piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the International Fuel Gas Code or International Plumbing Code as required by the application. Shut off all gas or fluid supply and depressurize the line before disassembly or fitting installation. Apply an approved thread sealant or PTFE tape to male threads before assembly and tighten to full thread engagement without over-torquing, which can crack the fitting body. Do not use this fitting beyond its rated pressure class.
