B K Mueller 568-040HN Galvanized Pipe Nipple 2x4 Inch

Product Description

The B K Mueller Industries 568-040HN is a galvanized steel pipe nipple sized at 2 inches in diameter by 4 inches in length. Pipe nipples are short threaded sections used to connect two fittings, valves, or other components within a piping system. This nipple features a hot-dip or mill galvanized zinc coating that provides corrosion resistance in exposed or moist environments. It is a standard close-coupled fitting used by licensed plumbers and pipefitters in water supply, gas distribution, and general-purpose piping assemblies. Each unit ships individually and is sold in a package quantity of 5.

This galvanized nipple is suited for residential and light commercial plumbing and mechanical systems where threaded steel pipe connections are required. Typical applications include water supply lines, heating system piping, compressed air distribution, and general utility piping in industrial or commercial settings. The galvanized finish makes it appropriate for outdoor, basement, or utility installations where bare steel would be prone to rust and early degradation.

Installation Notes

Installation of threaded pipe nipples should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Always shut off and depressurize the supply line before removing or installing any threaded fitting. Apply an approved thread sealant or PTFE tape to the male threads before assembly to ensure a leak-free connection. Do not over-tighten threaded connections, as this can crack fittings or damage threads.
