The Adaptall Series 9005ES Straight Male JIC x Male BSPP hydraulic adapters, made from durable carbon steel, are essential components designed for secure and efficient fluid connections in hydraulic systems. These adapters feature a male JIC (Joint Industry Council) end that utilizes 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. The seal is created by establishing contact between the male flared seat and the female coned seat, resulting in a robust mechanical connection. On the other end, the male BSPP (British Standard Pipe Parallel) connection is comparable to NPSM male fittings but typically features a different thread pitch. The 9005ES series includes an elastomeric seal, enhancing leak prevention through a captive seal created by metal-to-metal angled surfaces or a combination of metal and an O-ring. 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 as 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 that provide enhanced sealing performance in diverse applications.
