    1-1/4″ x 3″ Black Steel Pipe Nipple – Schedule 40, Welded, Grade B

    Part #: MM-57-123

    This 1-1/4″ x 3″ black steel pipe nipple is made from durable welded Schedule 40 steel and meets Grade B standards for dependable performance. It features precision-cut male National Pipe Taper (NPT) threads on both ends, ensuring a tight, leak-resistant fit. The black oxide finish provides basic corrosion resistance for non-potable, low-pressure applications. Commonly used for extending or connecting pipe in air, oil, gas, and steam systems.
