Asc Engineered Solutions 1B.NM45L 45 Deg Pipe Elbow 1-1/4 in

Product Description

The ASC Engineered Solutions 1B.NM45L is a 45-degree malleable iron pipe elbow designed to change flow direction in threaded pipe systems. Rated at 150 lb, it features a 1-1/4 inch female NPT (FNPT) connection on both ends. The galvanized finish provides corrosion resistance for use in wet or exposed environments. This fitting is domestically manufactured and suitable for gas, water, and air distribution systems. Licensed plumbers, pipefitters, and mechanical contractors install this type of fitting during new construction and retrofit work where a 45-degree directional change is required in a threaded iron pipe run.

This elbow is used in residential and light commercial plumbing, gas distribution, and HVAC piping applications. The 1-1/4 inch thread size is common in branch lines, main distribution runs, and mechanical room piping. The galvanized malleable iron construction makes it appropriate for both indoor and outdoor installations where moisture exposure is a factor. It threads directly onto standard NPT-compatible pipe, nipples, and fittings without adapters.

Key Features

• 45-degree bend angle for gradual directional changes in threaded pipe systems
• 1-1/4 inch FNPT connections 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 resists corrosion in damp or outdoor environments
• Domestically manufactured to support traceability and quality assurance requirements

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard 1-1/4 inch NPT threaded iron pipe systems rated at 150 lb class.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC or IFGC code requirements for the service type. Shut off and depressurize the pipe system completely before removing or installing any threaded fittings. Apply thread sealant or PTFE tape to male threads before assembly and tighten to hand-tight plus the appropriate number of turns for the pipe size and service. Do not over-torque malleable iron fittings, as the material can crack under excessive force.
