The Bore Through Male Connector (Metric Tube to NPT) is a precision-engineered instrumentation fitting designed to allow metric-sized tubing, thermocouples, or probes to pass entirely through the fitting body without the restriction of an internal tube stop. This unique bore-through design enables users to adjust the insertion depth of a probe or sensor to a specific point within a process line, making it indispensable for accurate thermal or analytical measurements. On the tube side, the fitting employs a high-performance double-ferrule compression system to provide a leak-proof, vibration-resistant seal once the desired position is reached, while the male NPT end features tapered threads for a secure, pressure-tight connection to a female port. Typically manufactured from 316 stainless steel for superior corrosion resistance and high-pressure integrity, these connectors are critical components in heat exchangers, temperature sensing applications, and analytical sampling systems where precise placement is essential for system performance.
