B K Mueller 510-305HN Galvanized Street Elbow 1 Inch

Product Description

The B K Mueller 510-305HN is a 1-inch galvanized steel street elbow rated at 90 degrees, used to change pipe direction in threaded plumbing and gas distribution systems. One end is male-threaded (street end) and the other is female-threaded, allowing direct connection to a fitting without a nipple. The galvanized finish provides corrosion resistance for wet or exposed environments. Licensed plumbers and pipefitters install this fitting in water supply, gas, and industrial piping systems where a compact directional change is needed.

This street elbow is suited for residential and light commercial plumbing, natural gas piping, compressed air lines, and general-purpose threaded pipe systems. It is commonly used in tight spaces where a standard elbow-plus-nipple combination would not fit. The 90-degree angle redirects flow perpendicular to the incoming pipe run. Installation follows standard NPT threading practices and applies to both new construction and retrofit service work.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable local codes and the International Plumbing Code (IPC) or International Fuel Gas Code (IFGC) where relevant. Shut off and depressurize the system completely before removing or installing any threaded fittings. Apply an approved pipe thread sealant or PTFE tape to male threads before assembly. Do not over-tighten fittings, as this can crack the fitting or damage the pipe thread.
