B K/mueller Inds(import) 511-974HN Galvanized Hex Bushing

Product Description

The B K/MUELLER INDS(IMPORT) 511-974HN is a galvanized hex bushing used to reduce a larger threaded pipe opening to a smaller threaded pipe connection. It features a male NPT thread on the outer end and a female NPT thread on the inner end, allowing it to serve as a threaded reducer fitting in piping assemblies. The galvanized steel construction provides corrosion resistance suited for exposed or moderately wet environments. At 1.5 inches by 0.75 inches, this bushing connects a 1.5-inch pipe to a 0.75-inch pipe run and is sized for use in plumbing, gas, and general pipe distribution systems. It is installed by licensed plumbers and pipefitters.

This hex bushing is used in residential and light commercial plumbing installations, gas distribution lines, and industrial piping systems where a threaded pipe size reduction is required. It fits standard NPT threaded pipe systems and is appropriate for applications where a compact, wrench-friendly hex profile is needed for tightening. The package includes 5 pieces per unit of measure, making it practical for job sites requiring multiple fittings of this size.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing and gas codes, including IPC and IFGC requirements. Shut off water or gas supply and depressurize the line before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Do not overtighten, as this can crack fittings or distort threads.
