The B K/MUELLER INDS(IMPORT) 510-204HN is a 3/4 inch galvanized steel 45 degree equal elbow designed for use in threaded pipe systems. It provides a 45 degree change in direction for pipe runs while maintaining a consistent bore diameter on both ends. The galvanized finish delivers corrosion resistance suited to water supply, gas distribution, and general-purpose piping applications. Plumbers and pipefitters install this fitting as part of new construction or repair work in both residential and light commercial systems. The equal-end configuration means both connection ports accept the same pipe size, simplifying layout and material selection on the job.
This elbow is used in threaded galvanized pipe systems commonly found in residential and light commercial plumbing, HVAC hydronic lines, and general industrial pipe runs. It is suited for applications requiring a moderate directional change without the sharper turn of a 90 degree elbow, which can help reduce flow restriction in certain layouts. Packaged in quantities of five per unit, it is practical for jobs requiring multiple fittings of the same size.
Designed as an OEM-style replacement fitting compatible with standard 3/4 inch NPT threaded galvanized pipe systems.
Installation is performed by licensed plumbers or pipefitters following applicable IPC and IFGC code requirements for the service type. Shut off and depressurize the pipe system fully before removing or installing any threaded fitting. Use appropriate pipe thread sealant or PTFE tape on all male threads before assembly. Do not overtighten threaded connections, as this can crack fittings or damage pipe threads.
