The X Nipple 15/20 is a male-to-male reducing connector used for connecting plumbing fittings or pipes of two different sizes. It features 15 mm threading on one side and 20 mm threading on the other, making it suitable for transition connections in bathroom, kitchen and general water-supply installations.

The precision-cut external threads help provide a firm and reliable fit, while the hexagonal centre section offers a convenient grip for installation using a spanner. Its strong metallic construction and corrosion-resistant finish make it suitable for regular domestic and commercial plumbing applications.
