3/8″ x 1/4″ Black Pipe Reducing Coupling – Female NPT

The 3/8″ x 1/4″ black pipe reducing coupling is engineered to connect two male-threaded pipes of different sizes in a straight-line configuration. Made from black malleable iron, it offers durability, corrosion resistance, and long-lasting performance in low-pressure systems. Precision-machined female NPT threads provide a tight, leak-resistant connection, making this coupling ideal for air, oil, gas, and steam applications in residential, commercial, and industrial systems.
