The pipe is made of 304-stainless steel, offering more than twice the strength of ordinary brass. It is resistant to acid, alkali, and salt, providing long-term corrosion resistance, which prevents the shower head from clogging due to rust residue. It features universal threading: 1/2 NPT, compatible with most standard showers. The thread contact surface is precision-cut, with a widened water outlet sealing surface to ensure a precise connection with the showerhead, fully compressing the gasket. Most customers can install it directly without worrying about using Teflon tape, preserving the product's appearance. The streamlined design complements various showerheads, and the included decorative cover conceals any extra holes. Installation is simple, requiring just a few minutes of twisting. Color: Brushed Nickel.
