The ASC Engineered Solutions C.NM45L is a 45-degree malleable iron pipe elbow designed to change flow direction in threaded piping systems. Rated at 150 lb and finished with a galvanized coating for corrosion resistance, this fitting accepts 3/8 inch female NPT connections on both ends. It is a domestically produced fitting suited for use in gas, air, water, and steam distribution lines where a 45-degree change in direction is required. Licensed plumbers, pipefitters, and HVAC technicians install this type of fitting during rough-in and retrofit work on threaded iron pipe systems.
This elbow is used in residential and light commercial piping applications including gas distribution, compressed air lines, hydronic heating systems, and general plumbing. The 3/8 inch FNPT thread size is common in branch lines and instrument connections. The galvanized finish provides added protection in installations where moisture exposure is a factor.
Designed as an OEM-style replacement or new-installation fitting compatible with standard 3/8 inch NPT threaded iron pipe systems rated for 150 lb service class.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing and mechanical codes. Shut off and depressurize the line completely before removing or installing any threaded fittings. Apply an approved thread sealant or PTFE tape to the male threads before assembly, and tighten to a snug fit using a pipe wrench without over-torquing the fitting. Verify system pressure rating is within the fitting class before returning the line to service.
