37° Flare Hydraulic Fittings is very common in fluid power systems

37° Flare Fittings 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.
flare tube fittings Applications:
For use with machine tools, agricultural and earth moving machinery, instrumentation, chemical processing systems, and most other high pressure hydraulic applications.
Pressure Ratings:
Working pressures up to 5000 PSI. Working pressures will vary depending on tube and fitting size. (For applications using extreme pressures at 5000 PSI or above, contact World Wide Fittings.)
