Schedule 40 Steel Pipe Nipple, 1-11-1/2 Male NPT, 4.50 Inch Long

For a 1-inch NPT line needing a 4.50-inch extension, this nipple fits that job well. The 1-11-1/2 male NPT threading on both ends connects standard 1-inch pipe fittings, and the 4.50-inch body length gives you that precise gap without having to cut or thread anything yourself. Schedule 40 wall thickness handles typical industrial pressures you'd see in that kind of setup.
