B K/mueller Inds(import) 511-976HN Galvanized Hex Bushing

Product Description

The B K/MUELLER INDS(IMPORT) 511-976HN is a galvanized hex bushing designed to reduce pipe thread connections from a larger nominal size to a smaller one. This fitting accepts a 1.5-inch male thread on the outer hex body and steps down to a 1.25-inch female thread at the center. The galvanized steel construction provides corrosion resistance suitable for water supply, gas distribution, and general piping systems. Plumbers and pipefitters install this bushing where a threaded reducer fitting is required in lieu of a reducing coupling. The hex profile allows for wrench engagement during installation, supporting proper torque without pipe damage.

This hex bushing is used in residential and light commercial plumbing systems, water service lines, and gas piping applications where a threaded pipe size reduction is needed at a fitting connection point. It is well suited for installations where the hex body must be wrench-tightened into a tee, coupling, or valve inlet. The galvanized finish makes it appropriate for exposed or semi-exposed installations where bare steel would be prone to surface corrosion.

Key Features

• 1.5-inch male NPT thread to 1.25-inch female NPT thread reduction

Compatibility

Designed as an OEM-style replacement fitting for threaded pipe systems requiring a 1.5-inch to 1.25-inch NPT hex bushing reduction in standard plumbing and gas piping configurations.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC or IFGC requirements. Shut off the water supply or gas service completely before threading this fitting into any live line. Apply appropriate thread sealant or PTFE tape to the male threads before installation. Do not over-tighten, as this can crack fittings or damage connected components.
