B K Mueller 560-040HC Galvanized Pipe Nipple 1/8x4

Product Description

The B K Mueller 560-040HC is a galvanized steel pipe nipple sized at 1/8 inch nominal diameter by 4 inches in length. Pipe nipples are short sections of threaded pipe used to connect two female-threaded fittings, valves, or equipment ports. The galvanized finish provides a zinc coating that resists corrosion in typical plumbing and light industrial environments. This nipple is installed by licensed plumbers, pipefitters, and mechanical contractors working on water supply, gas distribution, compressed air, or general fluid-handling systems where a close or short extension run is needed between components.

This 1/8 inch by 4 inch galvanized nipple is suited for residential and light commercial plumbing and mechanical systems. Common applications include connecting pressure gauges, condensate drain lines, gas appliance supply connections, and similar low-diameter branch runs. Its compact nominal bore makes it a frequent fit for instrumentation ports, pilot gas lines, and small-diameter auxiliary piping. Sold in a package quantity of 10 units, it is a practical stocking item for service vans and supply rooms.

Designed as a standard NPT-threaded galvanized pipe nipple for use in residential and light commercial plumbing, gas, compressed air, and general mechanical piping systems requiring a 1/8 inch nominal connection.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes, the International Plumbing Code (IPC), or International Fuel Gas Code (IFGC) as relevant to the service. Shut off the supply line and relieve all pressure before removing or installing any pipe nipple. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly, and do not overtighten, which can crack fittings or distort threads. Verify that the galvanized finish is compatible with the fluid or gas being conveyed per local code requirements.
