SAE J512, 45° Flare (SAE)
The SAE 45° flare connectors seal in the same manner and are similar to the 37° connectors except for the flare angle. When the straight threads are engaged, the 45° male seat seals on the 45° female flare seat. 45° connectors are commonly found in automotive and refrigeration applications, on brass adapters, and are generally used at lower pressures than 37° JIC connectors. Check the threads and flares carefully to make positive identification.
