The Series 6502-SS 45-Degree MJIC x Female JIC Swivel adapters, made from high-quality stainless steel, are crucial components for fluid power systems, particularly in hose end connections. These adapters feature male and female JIC (Joint Industry Council SAE J514) fittings, easily identified by their 37° tapered seats that form a mechanical seal when the male flared seat contacts the female coned seat. This secure connection style is commonly used in fluid power applications. It's important to distinguish between SAE J514 37° and SAE J512 45° connections, as they have different seat angles and should never be interchanged, as mixing them can cause leakage. Proper seat angle measurement is essential for ensuring a leak-free and reliable connection.
