The Series 9048 45-Degree Angled Male BSPP x Female BSPP Swivel Forged adapters are designed to provide secure, flexible connections in fluid power systems. These adapters feature male BSPP (British Standard Pipe Parallel) threads, similar to NPSM male connections, but with a different thread pitch, ensuring a leak-free seal. The male BSPP connection uses metal-to-metal angled surfaces or a combination of metal and an O-ring to form a captive seal. The female BSPP connection has a swivel design with a tapered nose flareless swivel, where the seal occurs on the male connector's cone seat. These adapters are ideal for applications that require strong, reliable connections, offering high-performance sealing. Because BSPP connections involve thread distortion for sealing, thread sealants are recommended for securing these connections. The adapters are commonly used in industrial fluid systems, and thread sizes are expressed using fractional dimensions with “G” for parallel threads, ensuring compatibility with a variety of fittings.
