Straight Female BSPP x Female NPT Rigid adapters in brass are fittings designed to connect British Standard Pipe Parallel (BSPP) and National Pipe Tapered (NPT) threaded components, commonly used in fluid and gas transfer systems. The BSPP connection features parallel threads, providing a seal through metal-to-metal contact or a combination of metal-to-metal and O-ring seals. The NPT connection uses tapered threads that deform to create a secure seal. These adapters are ideal for joining BSPP and NPT systems, but it’s important to use a thread sealant for optimal sealing performance. Brass is commonly used for low-pressure applications, offering a durable, corrosion-resistant solution for a wide range of industrial uses.
