Bmi Usa 10491 Black Steel Pipe Nipple 6 in 1/2 in 25 Pack

Product Description

The BMI USA 10491 is a black steel pipe nipple measuring 6 inches in length with a 1/2 inch NPT thread profile. Pipe nipples are short threaded pipe sections used to connect fittings, valves, and equipment in gas, water, and general plumbing distribution systems. This pack contains 25 assorted nipples, making it a practical bench or truck stock item for plumbers and pipefitters who regularly encounter 1/2 inch threaded connections. The black steel construction suits low-pressure gas piping and other applications where galvanized or stainless steel is not required. At 4.61 pounds for the pack, individual pieces are lightweight and easy to handle on the job.

These nipples are suited for residential and light commercial plumbing and gas piping installations. Common applications include natural gas supply lines, steam systems, air distribution, and hydronic heating piping where black steel is the specified material. The 25-piece assorted pack is well suited for service contractors, wholesale counter stock, or any job requiring a ready supply of 1/2 inch close-cut fittings. A licensed plumber or pipefitter should perform installation in compliance with applicable local codes.
