Brass Adapter, 1/2-14 Female NPT To 1/2-14 Male NPT, Straight

For tying two NPT pipe-threaded sides together, it’s a straight brass adapter with 1/2-14 female NPT on one side and 1/2-14 male NPT on the other, so it converts a 1/2-14 female connection into a 1/2-14 male connection.

Both threads on this adapter are 1/2-14 NPT, so yes, one end is female and the other is male. The whole point of a fitting like this is to reverse the thread gender at a connection point without changing the pipe size. It measures 1.31 inches in length and runs straight through, no angle or offset. Pretty handy when you've got two female-threaded ports that need to meet up or when a line terminates with the wrong gender for your fitting.
