45-Degree Angled Female JIC adapters are designed for fluid power systems, where they provide reliable, leak-free connections. These adapters feature female JIC (Joint Industry Council) 37° hydraulic connections, which are common in most hydraulic systems. The connection is made by the female coned seat meeting the male flared seat, forming a mechanical seal. This design ensures a secure and tight connection, essential for high-pressure fluid systems. It’s important to note that while SAE 37° and SAE 45° fittings have the same threads, their seat angles differ, and mixing the two can lead to leakage. Proper measurement of seat angles is essential for ensuring a reliable, leak-resistant connection.
