B K Mueller 561-025HC Galvanized Pipe Nipple

Product Description

The B K Mueller 561-025HC is a galvanized steel pipe nipple sized at 1/4 inch nominal diameter by 2-1/2 inches in length. Pipe nipples are short threaded pipe sections used to join fittings, valves, and other piping components in a run. The galvanized zinc coating provides corrosion resistance in exposed or damp environments. This nipple is a standard piece of hardware installed by licensed plumbers, pipefitters, and HVAC technicians during new construction, repair, or system modification work. It ships in a package quantity of 10 units.

This nipple is suited for use in residential and light commercial plumbing, gas distribution, and HVAC piping systems where a short threaded connector is required between two female-threaded components. The 1/4 inch nominal size is commonly found in low-pressure gas branch lines, compressed air distribution, and secondary water supply connections. Installation is straightforward and follows standard pipe-thread assembly practices.

Compatibility

Designed as a standard NPT threaded replacement or new-installation nipple for residential and light commercial plumbing, gas, and HVAC piping systems requiring 1/4 inch nominal pipe thread connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing and mechanical codes including the IPC and IFGC. Shut off the relevant water, gas, or air supply and depressurize the line before making any threaded connections. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly. Do not over-tighten threaded connections, as this can crack fittings or damage threads.
