    1/2″ x 3/8″ Black Pipe Reducing Coupling – Female NPT

    Part #: MM-65-435

    The 1/2″ x 3/8″ black pipe reducing coupling connects two male-threaded pipes of different sizes in a straight line. Manufactured from black malleable iron, this coupling ensures durability, strength, and resistance to corrosion in low-pressure systems. Precision-cut female NPT threads provide a secure, leak-resistant connection for a wide range of applications including air, gas, oil, and low-pressure steam systems.
