Asc D.BML 90 Degree Elbow 1/2 Inch Fnpt 150 Lb Malleable Iron

Product Description

The ASC Engineered Solutions D.BML is a 90-degree pipe elbow designed for threaded piping systems in plumbing, HVAC, gas distribution, and mechanical piping applications. Built from black malleable iron to a 150 lb pressure rating, this fitting accepts 1/2 inch female NPT connections on both ends and is domestically manufactured. Malleable iron construction provides the ductility needed to handle vibration and mechanical stress better than standard cast iron, making it a reliable choice in systems where rigid black iron pipe is the standard. Licensed plumbers, pipefitters, and HVAC technicians specify this fitting type for gas lines, steam systems, and compressed air distribution where a reliable directional change is required.

This elbow is suited for residential and light commercial black iron pipe installations. Common applications include natural gas and propane supply lines, low-pressure steam systems, and compressed air distribution. The 1/2 inch size is frequently used for branch lines feeding gas appliances such as furnaces, boilers, water heaters, and dryers. The black finish is standard for gas piping and distinguishes this fitting from galvanized fittings used in water service.

Key Features

• 90-degree directional change for black iron piping systems
• 1/2 inch FNPT threading on both ends for standard threaded pipe connections
• 150 lb pressure class malleable iron construction for durability and impact resistance
• Black finish standard for gas and mechanical piping applications
• Domestic manufacture

Compatibility

Designed as an OEM-style replacement or new-installation fitting compatible with standard 1/2 inch NPT threaded black iron pipe systems rated at 150 lb class.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable code requirements including IFGC and ASME B31 standards for gas and mechanical piping systems. Shut off and depressurize the line completely before disassembling or installing any threaded fitting. Apply an approved pipe thread sealant or PTFE tape rated for the intended service medium before making up connections. Do not over-tighten malleable iron fittings, as excessive torque can crack the casting.
