The Tube Cap (Metric Tube) is a high-performance instrumentation fitting designed to provide a permanent or temporary pressure-tight seal at the end of a metric-sized tube run. It utilizes a precision-machined nut and a robust double-ferrule compression system that securely grips the tubing to create a leak-proof, vibration-resistant closure capable of withstanding extreme pressure and vacuum conditions. While a plug is used to seal an unused fitting port, the tube cap is installed directly onto the tubing itself, making it indispensable for terminating lines, isolating sections of a system during maintenance, or protecting lines during pressure testing. Forged from 316 stainless steel for superior corrosion resistance and structural integrity, these caps are essential components in chemical processing, power plants, and high-precision fluid systems where reliable line isolation is critical.
