Our Series 9032 Straight Male BSPT x Female BSPP hydraulic adapters are used to connect a BSPT (British Standard Pipe Tapered) male threaded component to a BSPP (British Standard Pipe Parallel) female threaded port in hydraulic systems. The male BSPT threads are tapered, meaning they create a leak-tight seal by deforming the threads when tightened, while the female BSPP threads are parallel. These adapters rely on a metal-to-metal or metal-to-metal and O-ring seal, with sealing taking place at the conical seat of the male connector. Since BSPT and BSPP threads are close but not identical to NPT threads, thread sealants are recommended for securing the connection. BSPT male adapters are compatible with both BSPP and BSPT female ports. These adapters are ideal for ensuring secure and durable connections in various hydraulic applications. Thread sizes are typically expressed as fractional dimensions, with "R" denoting a tapered thread (e.g., BSPT 1/4-19 as R 1/4).
