The Adaptall Series 9005 Straight Male JIC x Male BSPP hydraulic adapters are vital components designed for fluid connections in hydraulic systems that require a robust and reliable mechanical interface without an integrated seal. 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 common in fluid power systems for their durability and efficiency. The seal is established through 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 similar to NPSM male fittings but generally features a different thread pitch. A captive seal is achieved using metal-to-metal angled surfaces, ensuring a secure connection. The female swivel BSPP includes 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 dependable hydraulic solutions in diverse applications.
