The Bulkhead Male Connector (Metric Tube to NPT) is a precision-engineered instrumentation fitting designed to provide a leak-proof transition from metric tubing to a female NPT threaded port through a panel or bulkhead. It features an elongated, threaded body and a specialized locknut that allows the fitting to be rigidly secured to an enclosure, ensuring mechanical stability and protecting the tubing from stress or vibration at the penetration point. The tube side utilizes a high-performance double-ferrule compression system to provide a torque-free seal capable of withstanding high pressures, while the male NPT end features tapered threads for a secure, pressure-tight connection. Typically forged from 316 stainless steel, these connectors are essential for creating professional and organized layouts in industrial control panels, water treatment systems, and fluid processing plants.
