The Male Tube Adapter (Metric Tube to NPT) provides a reliable, leak-proof transition between metric tubing and a female NPT port. It features a smooth tube stub designed to be gripped by a standard compression fitting and a male NPT threaded end for secure connection to valves or manifolds. This “swing-free” design simplifies installation in tight spaces by allowing the adapter to be threaded into a port independently of the tubing. Typically made from 316 stainless steel, it is essential for high-pressure industrial and analytical systems where precision alignment and corrosion resistance are required.
