B K/mueller Inds(import) 511-387HN Galvanized Reducing Coupling

Product Description

The B K/MUELLER INDS(IMPORT) 511-387HN is a galvanized reducing coupling designed to connect a 2-inch pipe to a 1-1/2-inch pipe in threaded steel piping systems. The coupling is manufactured with a galvanized finish to resist corrosion in exposed or mildly harsh installation environments. This type of reducing coupling is a standard fitting used by plumbers and pipefitters to transition between two different nominal pipe sizes within the same run. The galvanized steel construction makes it appropriate for water, gas, and general-purpose piping applications where a durable, threaded connection is required.

This reducing coupling is suited for residential and light commercial plumbing and mechanical piping systems. It is commonly installed in supply lines, distribution headers, and branch connections where a pipe run must step down from 2-inch to 1-1/2-inch nominal pipe size. Plumbers and pipefitters install this fitting during new construction and retrofit work. It is sold in a package quantity of 5 units, making it practical for jobs requiring multiple fittings of the same size.

Key Features

• Reduces from 2-inch to 1-1/2-inch nominal pipe size in a single threaded fitting
• Galvanized steel finish provides corrosion resistance for exposed and moderate-duty environments
• Threaded ends accept standard NPT pipe threads for secure, leak-resistant connections
• Sold in a package of 5 units for multi-fitting installations
• Suitable for water, gas, and general mechanical piping applications

Compatibility

Designed as an OEM-style replacement or standard trade fitting for threaded galvanized steel piping systems using 2-inch and 1-1/2-inch nominal pipe sizes.

Installation Notes

This fitting is installed by licensed plumbers or pipefitters working on threaded steel pipe systems. Always shut off and depressurize the affected piping system before removing or installing any fitting. Apply an appropriate pipe thread sealant or PTFE tape to all male NPT threads before assembly. Work must comply with applicable local plumbing codes and the International Plumbing Code where adopted.
