USA Manufactured Black Cast Iron 45° Drainage Pipe Street Elbow

USA Manufactured Black Cast Iron 45° Drainage Pipe Street Elbow

USA Manufactured Black Cast Iron 45° Drainage Pipe Street Elbows provide a durable, compact solution for changing the direction of drain, waste, and vent piping. Manufactured in the United States from quality black cast iron, these specialty drainage fittings typically feature one male NPT connection and one female NPT connection, allowing direct installation into another threaded fitting without requiring an additional close nipple.

The 45-degree street-elbow pattern creates a gradual directional change that helps maintain efficient gravity flow while reducing turbulence compared with sharper turns. Its male-by-female configuration can shorten the completed piping assembly, reduce the number of threaded joints, and conserve valuable space in crowded mechanical rooms, wall cavities, equipment areas, and industrial drainage installations.

Compact Male-by-Female Drainage Connection

Black cast iron provides excellent rigidity, dimensional stability, mechanical durability, and natural sound-dampening performance. USA manufactured black cast iron drainage street elbows offer dependable dimensions and precision-machined tapered threads for professional installation.

The male threaded end installs directly into a compatible female NPT fitting, while the female end accepts male NPT drainage pipe, a nipple, or an adapter. A suitable pipe-thread sealant should be applied according to the installation requirements. These fittings are generally designed for non-pressure gravity drainage service, and selection should follow applicable plumbing codes, flow requirements, and system specifications.
