Asc Engineered Solutions 1.NM45L 45 Deg Elbow 1 in Fnpt 150 Lb

Product Description

The ASC Engineered Solutions 1.NM45L is a 45-degree malleable iron pipe elbow designed for use in low-pressure gas, water, and air piping systems. Sized at 1 inch with female NPT (FNPT) threads on both ends, it is rated at 150 lb and carries a galvanized finish for added corrosion resistance. This fitting is domestically produced and intended for installation by licensed plumbers, pipefitters, and HVAC technicians working on threaded pipe assemblies where a 45-degree directional change is required.

This elbow is suited for residential and light commercial applications including gas distribution lines, water supply piping, compressed air systems, and hydronic heating runs. The FNPT thread pattern makes it compatible with standard NPT-threaded pipe and fittings in 1-inch nominal pipe size. Its galvanized coating makes it a practical choice in exposed or moderately corrosive environments where bare iron would be prone to surface rust.

Key Features

• 45-degree elbow geometry for angled directional changes in threaded pipe runs
• 1-inch FNPT threads on both ends for standard NPT pipe compatibility
• 150 lb pressure rating suitable for low-pressure gas, water, and air service
• Malleable iron construction provides strength and resistance to mechanical stress
• Galvanized finish delivers corrosion protection in exposed or damp environments
• Domestic manufacture

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-inch nominal threaded pipe systems using standard NPT connections rated at 150 lb class.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the IPC or IFGC. Shut off 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 hand-tight plus the appropriate number of turns using a pipe wrench — do not overtighten malleable iron fittings. Verify system pressure and inspect for leaks after restoring service.
