Black Iron Nipple

This black iron nipple is made from corrosion-resistant malleable iron, so it provides long-lasting durability in a variety of environments with high humidity and salt spray content. Due to the high strength of malleable iron, this product is highly resistant to liquid obstruction and pressure, providing excellent performance in a variety of high-pressure pipelines. After surface treatment such as hot-dip galvanizing and cold-dip galvanizing, it becomes more wear-resistant and corrosion-resistant while obtaining a more exquisite appearance. In addition, these nipples have passed UL certification, FM certification, CE, ABNT and other certifications, see the figure below for details. We can also customize sizes, materials and standards for customers. Customers in need are welcome to consult!
