Asc Engineered Solutions 1B.BM45L 45 Deg Pipe Elbow 1-1/4 in

Product Description

The ASC Engineered Solutions 1B.BM45L is a 45-degree malleable iron pipe elbow designed for threaded piping systems in commercial and industrial applications. Rated at 150 lb and threaded with female NPT connections on both ends, this fitting redirects pipe runs at a 45-degree angle without requiring welding or special tooling. The black finish is standard for gas distribution and mechanical piping applications. At 1-1/4 inches, it fits a common pipe size used across a wide range of plumbing, HVAC, and gas piping systems. Malleable iron construction provides the durability and thread integrity that licensed plumbers and pipefitters expect from a pressure-rated fitting on the job.

This elbow is suited for residential and light commercial piping installations where a 45-degree directional change is needed in a threaded iron pipe system. Common applications include natural gas and propane distribution lines, steam and condensate systems, and general mechanical piping. The black finish and 150 lb pressure rating make it a standard choice for gas supply roughing work. It is domestically produced, meeting procurement requirements for projects that specify domestic-origin fittings.

Key Features

• 45-degree angle redirects pipe runs with minimal pressure drop compared to a 90-degree fitting
• Female NPT (FNPT) threads on both ends for standard threaded pipe connections
• 150 lb pressure rating suitable for gas, steam, and mechanical piping applications
• Malleable iron construction resists cracking and deformation under mechanical stress
• Black finish is compatible with gas piping systems per standard trade practice
• Domestically manufactured for projects with domestic-origin material requirements

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-1/4 inch threaded iron pipe systems rated at 150 lb, including gas, steam, and general mechanical piping configurations.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes, including the IFGC for gas piping or the IPC for plumbing systems. Shut off and isolate the gas or fluid supply and verify zero pressure before disassembling any existing piping. Apply an appropriate thread sealant or PTFE tape rated for the intended service medium before making up threaded connections. Do not overtighten malleable iron fittings, as excessive torque can crack the casting.
