This plumbing valve accessory set includes 3 standard adapters that convert G1/2 British straight thread to 1/2 NPT, built with a one-piece solid brass body that contains no plastic components to prevent common issues like aging, cracking or leakage after long term contact with running water. All temperature markings on the surface use fahrenheit units, with the adjustable outlet water temperature ranging from 68°F to 122°F to fit most daily domestic water use needs. To set a water temperature higher than 100°F, users only need to press the built-in red button while slowly rotating the valve body. The whole set fits most conventional plumbing systems, and can be installed for use on wash basins, bidets, shower fixtures, different bathroom spaces and kitchen water lines for regular temperature regulation.
