An NPT‑M x BSPP‑M male hex nipple is a precision-engineered pipe fitting designed to connect a female NPT-threaded port to a female BSPP-threaded port in a straight-line configuration. It features male NPT threads on one end and male BSPP threads on the other, with a central hexagonal section for easy tightening or removal with a wrench. This fitting ensures a secure, leak-resistant connection between NPT and BSPP systems where compatibility is required.
These fittings are widely used in hydraulic, pneumatic, instrumentation, and fluid systems across industries such as oil and gas, chemical processing, power generation, and manufacturing. When installed with proper thread sealant or O-ring (for BSPP end), the connection provides reliable sealing suitable for high-pressure and demanding operational conditions.
