1″ Black Pipe Coupling – Female NPT

The 1″ black pipe coupling is used to join two male-threaded pipes in a straight configuration. Made from durable black malleable iron, this coupling provides strength and corrosion resistance for low-pressure applications. Its precision-cut female NPT threads ensure a secure and leak-resistant connection, making it an ideal choice for air, gas, oil, and steam piping systems in industrial, commercial, and residential settings.
