Hongxin Pipes & Fittings provides different types of nipple fittings according to the needs of hardware customers.
A nipple is a short segment of pipe with equal male threading at each end. It is typically used for connecting two other pipes, fittings or hoses.
Pipe nipples can be made from a wide range of materials, including carbon steel, brass, stainless steel, aluminum and more. Using pipe nipples makes it possible to position tubing exactly where it is needed.
Pipe nipples also come with a variety of end finishes, such as tapered thread, straight thread, roller cut, reamed and chamfered, square cut, and grooved.
