A reducing bushing NPT‑M x BSPT‑F is a precision-engineered pipe fitting designed to connect a male NPT-threaded port to a female BSPT-threaded port of a smaller size, allowing a reduction in pipe or tubing diameter while maintaining a secure, leak-resistant connection. It features male NPT threads on the outside and female BSPT threads on the inside, with a hexagonal body for easy tightening or removal with a wrench.
These bushings are commonly used in hydraulic, pneumatic, instrumentation, and fluid systems where components with different threading standards (NPT and BSPT) need to be joined. When installed with appropriate thread sealant or PTFE tape, the combination of NPT taper and BSPT taper threads provides a reliable, high-pressure seal suitable for demanding industrial applications.
