Our Straight Male BSPT x Male BSPT Nipple hydraulic adapters are designed to connect two BSPT (British Standard Pipe Tapered) male threads. BSPT connections, similar to NPT, feature tapered threads that create a seal through the distortion of the threads themselves. Because of this, thread sealants are often recommended to ensure a tight, leak-proof connection. These adapters are used for applications that require a metal-to-metal seal, often with the help of an O-ring. The male BSPT threads are compatible with both BSPT and BSPP (British Standard Pipe Parallel) female ports, offering versatility for various hydraulic systems. Thread sizes are typically expressed in fractional dimensions, with BSPT threads denoted by "R," for example, BSPT 1/4-19 can be designated as R 1/4.
