Straight Female BSPP (British Standard Pipe Parallel) adapters are fittings used to connect BSPP threaded components in fluid and gas systems. BSPP threads are similar to NPT threads but have a different thread pitch, making them slightly incompatible with NPT components. The BSPP male connector has parallel threads and a captive seal that is created by metal-to-metal contact or a combination of metal-to-metal and O-ring seals. These adapters are commonly used for applications where a secure, leak-proof connection is required. It’s important to use thread sealants to ensure a reliable seal due to the thread distortion during connection. BSPP connections are similar to American NPSM male threads but are not interchangeable, offering a robust sealing solution for various industrial applications.
