The Adaptall Series 9240 Straight Male JIC x Female BSPP swivel hydraulic adapters are essential components designed for secure and flexible fluid connections in hydraulic systems. Featuring a male JIC (Joint Industry Council) end, these adapters utilize a 37-degree flare seating surface and parallel threads, as defined by SAE J514, which are commonly used in fluid power applications for their reliability and strength. The seal is established through contact between the male flared seat and the female coned seat, resulting in a robust mechanical connection. The female BSPP (British Standard Pipe Parallel) connection is comparable to NPSM male fittings but typically has a different thread pitch, ensuring compatibility in various applications. A captive seal is achieved using metal-to-metal angled surfaces or a combination of metal and an O-ring, providing a leak-proof connection. The female swivel BSPP features a tapered nose flareless swivel, allowing for movement and alignment during installation while maintaining a secure seal on the cone seat of the male connector. Thread sizes are often expressed in fractional dimensions preceded by "G" for parallel threads and "R" for tapered threads, facilitating easy identification and compatibility. These adapters are ideal for professionals seeking efficient and reliable hydraulic solutions in a wide range of applications.
