B K Mueller 582-025HC Black Pipe Nipple 3/8x2-1/2 10-pack

Product Description

The B K Mueller Industries 582-025HC is a black steel pipe nipple sized at 3/8 inches by 2-1/2 inches. Pipe nipples are short threaded pipe segments used to connect fittings, valves, and equipment in gas, air, and fluid distribution systems. This nipple ships in a package quantity of 10 units, making it suitable for contractors completing multi-point installations. The black finish indicates an uncoated steel construction standard for gas piping applications. Licensed plumbers and pipefitters install these components during rough-in and service work on low-pressure gas and mechanical systems.

This nipple is commonly used in residential and light commercial piping installations, including natural gas supply lines, propane distribution, compressed air systems, and general black iron piping assemblies. Its 3/8-inch diameter is a standard size found throughout residential gas appliance connections and branch supply runs. Contractors often keep a stock of assorted nipple sizes on hand for service calls and new construction rough-in work where field-cut lengths are not practical.

Installation Notes

Black iron pipe nipples are installed by licensed plumbers or pipefitters in accordance with local codes and the International Fuel Gas Code (IFGC) for gas service applications. Shut off the gas supply and verify zero pressure at the line before making or breaking any connections. Apply an approved pipe thread sealant or PTFE tape rated for gas service to all threaded joints before assembly. Do not over-tighten threaded connections; follow fitting manufacturer guidelines and inspect all joints for leaks after restoring service pressure.
