The Series 9058 45-Degree MJIC x Male BSPP Adjustable Elbow adapters, made from durable carbon steel, are designed for fluid power systems, particularly in hose end connections. These adapters feature male JIC (Joint Industry Council SAE J514) fittings with 37° tapered seats, creating a secure mechanical seal when the male flared seat meets the female coned seat. The male BSPP (British Standard Pipe Parallel) connection is similar to NPSM and forms a seal using metal-to-metal angled surfaces or a combination of metal-to-metal and an O-ring. While BSP and BSPT threads resemble NPT threads, they have different thread pitches and require thread sealants for a secure connection. It is important to avoid mixing SAE 37° and SAE 45° fittings due to their differing seat angles, which can lead to leakage. Proper measurement of seat angles and thread size is critical for ensuring leak-free, effective connections in fluid power applications.
