Female JIC Rigid and Swivel adapters are components used in fluid power systems for secure hose and pipe connections. These adapters feature a 37° tapered seat that creates a mechanical seal when the male flared fitting makes contact with the female coned seat. The JIC (Joint Industry Council SAE J514) connection style is commonly used in hydraulic systems, providing reliable, leak-free performance. It's important to note that SAE J514 (37°) fittings should not be mixed with SAE J512 (45°) fittings, as the different seat angles can lead to leaks. Available in various sizes like -02, -03, and -04, these fittings are crucial for ensuring the integrity and efficiency of fluid power systems.
