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