Asc D.NML 90 Degree Elbow 1/2 in Fnpt 150 Lb Malleable Iron

Product Description

The ASC Engineered Solutions D.NML is a 90-degree pipe elbow rated for 150 lb service, sized at 1/2 inch with female NPT (FNPT) threading on both ends. Constructed from malleable iron with a galvanized finish, this fitting provides corrosion resistance suitable for a range of fluid and gas piping applications. The galvanized coating helps protect against oxidation in moderately corrosive environments. This elbow is a domestically manufactured fitting intended for installation by licensed plumbers, pipefitters, and mechanical contractors working on low-pressure piping systems.

This fitting is used in residential and light commercial piping systems where a 90-degree directional change is required in a 1/2 inch threaded pipe run. Common applications include natural gas distribution piping, steam and hot water heating systems, compressed air lines, and water supply piping. The FNPT connections allow direct assembly onto standard male NPT threaded pipe using pipe thread sealant or PTFE tape. The 150 lb pressure class makes it appropriate for standard low-pressure mechanical piping installations.

Key Features

• 90-degree elbow geometry for right-angle directional changes in pipe runs
• 1/2 inch FNPT threading on both ends for standard NPT male pipe connections
• 150 lb pressure class rating suitable for low-pressure gas, steam, air, and water service
• Malleable iron construction provides strength and impact resistance over cast iron
• Galvanized finish delivers corrosion protection for extended service life
• Domestically manufactured to standard pipe fitting dimensions

Compatibility

Designed as an OEM-style replacement and new-installation fitting compatible with standard 1/2 inch male NPT threaded pipe in 150 lb malleable iron piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the IPC or IFGC. Apply an appropriate pipe thread sealant or PTFE tape to the male NPT threads before assembly. Hand-tighten first, then use a pipe wrench to achieve a proper thread engagement without over-torquing. Shut off and depressurize the piping system completely before removing or installing any threaded fittings.
