    1-1/4″ x 2″ Black Steel Pipe Nipple – Schedule 40, Welded, Grade B

    Part #: MM-57-121

    This 1-1/4″ x 2″ black steel pipe nipple is built from welded Schedule 40 steel and meets Grade B standards for strength and reliability. It features male National Pipe Taper (NPT) threads on both ends for secure, leak-resistant connections. The black oxide coating provides basic corrosion resistance, making it suitable for non-potable low-pressure applications. Ideal for extending or joining black pipe in air, oil, gas, and steam systems.
