Straight Male BSPT hydraulic adapters are used to connect hydraulic systems with tapered threads, ensuring a secure seal. British Standard Pipe Tapered (BSPT) threads are similar to NPT but have a slightly different thread pitch and form. The sealing process occurs through the deformation of the threads, making thread sealant necessary to prevent leaks. These adapters feature a captive seal, typically created using metal-to-metal angled surfaces or an O-ring, which ensures a tight connection when the adapter is tightened. BSPT male adapters are compatible with both BSPT and BSPP female ports. BSPT thread sizes are expressed as fractional dimensions, with “R” denoting a tapered thread, such as R 1/4 for BSPT 1/4-19. These adapters are ideal for applications that require a leak-proof seal and reliable connection between components with different thread styles.
