The Series 8043 Straight Female BSPP x Female BSPP Coupling Adapters in brass are durable fittings used to connect two BSPP (British Standard Pipe Parallel) threaded components in fluid and gas systems. BSPP threads, while similar to NPT threads, have a different thread pitch and are not fully interchangeable. These adapters create a reliable, leak-proof seal through metal-to-metal contact or a combination of metal-to-metal and O-ring seals. The female BSPP connectors feature a tapered nose flareless swivel that seals when the male connector’s cone seat makes contact. Made from brass, these adapters are ideal for low-pressure applications, offering corrosion resistance and strength. It is recommended to use thread sealants to ensure optimal sealing due to thread distortion during connection.
