90-Degree Angled Male JIC hydraulic adapters are crucial for creating reliable, leak-free connections in fluid power systems, particularly in hose end connections. Both male and female JIC (Joint Industry Council SAE J514) components are easily identified by their 37° tapered seats, forming a strong, mechanical seal when the male flared and female coned seats meet. These adapters are designed for high-pressure systems, with a working pressure rating up to 5000 psi. It’s important to note that while SAE 37° and SAE 45° fittings share the same threads, they have different seat angles—intermixing the two can lead to leaks. The JIC style sold on OneHydraulics.com is the 37° configuration, commonly used in fluid power systems, and ensures optimal performance when correctly matched with compatible fittings.
