Swaged Nipple is a reducing pipe nipple, used to connect two different sized fittings. A swaged pipe nipple, also called swage fitting or reduced nipple, is one that allows reductions to be made by taking the flow from one pipe diameter to a different one and they can be concentric or eccentric depending on the type of connection to be made.Eccentric Swage Nipple has one end larger in diameter than the other, making it ideal for applications where a reduction in pipe size is needed without changing the overall length of the pipe. In contrast, a Concentric Swage Nipple has both ends with the same diameter, maintaining a constant size throughout the length of the swage. This type is suitable when a reduction in size is required, and the overall length is not a critical factor.
