The Series 2505 45-Degree MJIC x Female NPT Rigid adapters, made from durable carbon steel, are essential components for fluid power systems, especially in high-pressure applications. These adapters combine the popular 37° male and female JIC (Joint Industry Council SAE J514) connections, recognized by their tapered seats, with a female NPT (National Pipe Tapered) thread. The JIC connection forms a mechanical seal when the male flared seat meets the female coned seat, ensuring a secure fit. NPT threads are widely used for pipe connections to seal fluid and gas transfers, with a tapered design that provides a reliable leak-proof seal. Care should be taken to avoid mixing SAE 37° and SAE 45° fittings, as they have different seat angles, which could cause leakage.
