The Adaptall Series 9002 Straight Male JIC x Male BSPP hydraulic adapters are essential components designed for secure and efficient fluid connections in hydraulic systems. Featuring a male JIC (Joint Industry Council) end on one side, these adapters utilize 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 formed by establishing contact between the male flared seat and the female coned seat, creating a robust mechanical connection. On the other side, the male BSPP (British Standard Pipe Parallel) connection is comparable to NPSM male fittings but typically features 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 secure connection. The female swivel BSPP incorporates 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, ensuring compatibility with various systems. These adapters are ideal for professionals seeking reliable hydraulic solutions in diverse applications.
