The ASC Engineered Solutions 310023007 is a black malleable iron 45-degree elbow fitting designed for threaded pipe assemblies in plumbing, HVAC, and gas distribution systems. The 1/4-inch fitting accepts standard NPT-threaded pipe and redirects flow at a 45-degree angle, making it suited for branch offsets and diagonal runs where a 90-degree elbow would be too abrupt. The black coating provides corrosion resistance and is standard for gas piping applications. At 0.11 pounds, the fitting is compact and easy to handle during installation.
This 45-degree elbow is used in residential and light commercial applications including natural gas and propane supply lines, compressed air systems, and general-purpose black iron pipe assemblies. It is appropriate wherever a low-profile directional change is needed in a 1/4-inch threaded iron pipe run. Plumbers, pipefitters, and HVAC technicians routinely specify black malleable iron fittings for gas service due to their strength and compatibility with standard pipe thread sealants.
Designed as an OEM-style replacement or new-installation fitting for 1/4-inch NPT threaded black iron pipe systems in residential and light commercial gas, air, and fluid service applications.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes including the IFGC for gas service or IPC for plumbing applications. Shut off and depressurize the pipe system completely before disassembling or adding fittings. Apply an approved thread sealant or pipe tape to the male threads before assembly and tighten to a snug, leak-free connection using a pipe wrench. Do not overtighten malleable iron fittings, as the material can crack if excessive torque is applied.
