37° Flare (JIC) Hydraulic Fittings (SAE J514)
This Connection is very common in fluid power systems. Both the male and female halves of the connections have 37° seats. The seal takes place by establishing a line contact between the male flare and the female cone seat. The threads hold the connection mechanically. CAUTION: in the -02, -03, -04, -05, -08, and -10 sizes, the threads of the SAE 45° flare and the SAE 37° flare are the same. However, the sealing surface angles are not the same.
