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

    Part #: MM-57-103

    This 3/4″ x 3″ black steel pipe nipple is constructed from welded Schedule 40 steel and meets Grade B standards for strength and durability. Featuring National Pipe Taper (NPT) male threads on both ends, it ensures a tight, leak-resistant fit in piping assemblies. The black oxide coating provides added corrosion resistance in non-potable applications. Suitable for low-pressure systems involving air, oil, gas, and steam.
