The THREAD 1/2″ x 1/8″ Brass Bush (BRBUSH-DA) is a precision-machined, hexagonal brass reducer that converts a 1/2″ BSP male thread to a 1/8″ BSP female thread, ideal for adapting fittings or reducing pipe size. Made from quality brass, it offers corrosion resistance and a reliable, leak-tight connection without the need for soldering — perfect for hot or cold water systems, boilers, radiators, or other plumbing and heating applications.
