Female Connector (ISO Tapered – RT)

ISO Tapered - RT

The Female Connector (ISO Tapered – RT) is a high-precision instrumentation fitting designed to establish a secure, leak-proof transition between fractional or metric tubing and a male ISO tapered threaded component. It features a robust double-ferrule compression design on the tube side, which provides a vibration-resistant, torque-free seal capable of maintaining high-pressure integrity even in demanding industrial environments. The opposite end is machined with internal (female) ISO tapered threads (RT/PT), which utilize a metal-to-metal tapered interface—often requiring a thread sealant—to ensure a pressure-tight connection with mating male pipes or valves. Typically manufactured from 316 stainless steel or other high-grade alloys, these connectors are essential in global fluid systems, chemical processing, and power generation plants where adherence to international ISO threading standards is required for reliable system performance.
