The Series 2504 45-Degree Male JIC x Male JIC Rigid adapters, made from durable carbon steel, are essential for fluid power systems, especially in hose end connections. These adapters feature male JIC (Joint Industry Council SAE J514) fittings, easily identified by their 37° tapered seats. The connection forms a reliable seal when the male flared seat contacts the female coned seat, creating a secure mechanical connection. These adapters are commonly used in fluid power applications, but it is crucial to distinguish between SAE 37° and SAE 45° fittings, as mixing them can cause leakage due to differing seat angles. Proper measurement of seat angles ensures a leak-free, high-performance connection.
