    3/8″ Black Pipe Coupling – Female NPT

    Part #: MM-65-412

    The 3/8″ black pipe coupling connects two male-threaded pipes in a straight run. Constructed from black malleable iron for durability, it is designed for low-pressure piping applications. The female NPT threads deliver a secure, leak-resistant connection, making it ideal for extending pipe systems in residential, commercial, and industrial environments.
