ENGA Brass 12-Inch Ceiling Mount Shower Arm (Brushed Nickel)

Excellent Corrosion Resistance: Quality brass uses electroplating (Brushed Nickel) to separate water from the metal. With intact plating, it resists corrosion well in neutral or hard tap water. Stainless steel may corrode in some water supplies. | Long-Term Stability: Brass has a similar thermal expansion to wall pipes, reducing stress and loosening during temperature changes. In contrast, stainless steel is excessively rigid, and repeated thermal cycles may increase the risk of joint leakage over time. | Solid Brass Construction: The entire brass component is seamless and requires no welding, whereas stainless steel pipes need welding. The welded joints are susceptible to corrosion over time. | CollocationThis square shower extension arm work for 6",10",12",16" rain shower head. | US standards: 1/2 inch threads work with standard American rainshower.
