The Female Connector (Metric Tube to NPT) is a high-precision instrumentation fitting designed to provide a leak-proof, torque-free connection between metric-sized tubing and male NPT pipe threads. Typically manufactured from durable materials like 316 stainless steel or brass to withstand high-pressure and corrosive environments, these connectors utilize a compression-style ferrule system on the tube side to ensure a secure mechanical grip. They are essential in industrial fluid systems, such as valve instrumentation and water purification plants, where transitioning from standard metric lines to threaded components like gauges, transmitters, or sensors requires a reliable, vibration-resistant seal.
