Welcome to our shop We are excited to introduce our universal tube with a diameter of 50mm and 75mm. This tube is designed to fit most newly remodeled homes. Made of brass material, it features a casting brass body which ensures durability and makes it not easy to break. The tube is equipped with a thickened board, providing resistance against external forces. It also has a double-layer skimming design with a built-in skimming cup cover, effectively reducing blockage. The hollow-out panel allows for large displacement without standing water, ensuring fast drainage. To enhance its appearance, the tube undergoes a multi-layer plating process, resulting in a bright and shiny surface that is non-perishable. We guarantee detailed and accurate product dimensions, as well as the delivery of the specified quantity. Note: 1. Please allow small size error due to manual measurement.
