The Adaptall Series 9002 Straight Male JIC x Male BSPP hydraulic adapters, made from high-quality stainless steel, are essential components for creating secure fluid connections in hydraulic systems. These adapters feature a male JIC (Joint Industry Council) end on one side, utilizing a 37-degree flare seating surface and parallel threads as defined by SAE J514, which are widely used in fluid power systems for their durability and reliability. The seal is established by contact between the male flared seat and the female coned seat, creating a strong mechanical connection. On the other side, the male BSPP (British Standard Pipe Parallel) connection is comparable to NPSM male fittings but typically has a different thread pitch. A captive seal is achieved using metal-to-metal angled surfaces or a combination of metal and an O-ring, ensuring a leak-proof connection. The female swivel BSPP features a tapered nose flareless swivel, where the seal occurs 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, allowing for easy compatibility with various systems. These adapters are ideal for professionals seeking reliable hydraulic solutions in a wide range of applications.
