Brass Inverted Flare Fittings (SAE J512 Inverted)
This connection is frequently used in automotive systems. The male connector can either be a 45° Flare in the tube fitting form or a 42° seat in the machined adapter form. The female has a straight thread with a 42° inverted flare. The seat takes place on the flared surfaces. The threads hold the connection mechanically.
