System1 Designs Performance fittings are produced right here in the USA by one of the top manufacturers in the industry. With the System1 Designs team having many years in the field, we have used our fair share of plumbing components over time and we are confident we found the best product to fit the bill. These fittings are made out of high quality material, precision machined, and anodized PROPERLY. This means you dont have to worry about them breaking, leaking, or fading over the years. They are HIGHLY resistant to scratching, which is one of our biggest concerns beyond how they perform.
