“Unlike the male nipple, a female nipple has female threads on both ends. This means that it can be used to connect two male-threaded pipes or fittings together.
Just like with male nipples, it’s essential to ensure that the thread size and type on both ends of the female nipple match the male-threaded pipes or fittings you intend to connect. This ensures a proper and secure connection that will prevent leaks and ensure the integrity of the plumbing system.”
