The Series 6502 angled 45-Degree MJIC x Female JIC Swivel adapters, made of durable carbon steel, are essential components in fluid power systems, particularly for hose end connections. These adapters feature male and female JIC (Joint Industry Council SAE J514) connections, recognized by their 37° tapered seats that form a mechanical seal when the male flared seat contacts the female coned seat. This reliable connection style is widely used in fluid power applications. It's important to note that while SAE J514 37° and SAE J512 45° connections may appear similar, they have different seat angles and cannot be interchanged, as mixing them can lead to leakage. Proper measurement of seat angles is crucial to ensure a secure, leak-free connection.
