I had to connect a 3/8 male power steering hose to a 3/8 male power steering pump. Thanks for the inverted flash image. The SAE flare connection looks like a volcano on either side. The 3/8 connection thread is 5/8-18. There are other unions with a similar description and generic image. But they are designed for a DIN socket that looks like a funnel on both sides. Can't use them for my application.
