150lb BSP Hex Union Coupling Adaptor-3/8" F to 3/8" F

The primary purpose of a hex union coupling is to provide a convenient way to disconnect two pipes or sections of a pipeline. This can be useful for maintenance, repairs, or replacing components within the system. Instead of cutting the pipes and adding new fittings, you can simply unscrew the hex nut to separate the pipes, and later, reattach them easily.
