This 1-1/4" black malleable steel closed nipple is a high-strength plumbing and gas fitting designed for professional appliance installations and industrial piping systems. Manufactured from durable malleable iron, this fitting is specifically engineered for gas supply lines, steam heating, and low-pressure liquid applications. As a 'close' nipple, it features continuous threading from end to end, allowing for the tightest possible connection between two female-threaded components. This makes it an essential part for gas ranges, boilers, and commercial water heaters where space is at a premium. Its black finish provides natural resistance to corrosion in non-potable water and gas environments, ensuring a secure, leak-proof seal for heavy-duty appliance operation.
