The Bulkhead Reducing Union (Metric Tube) is a specialized instrumentation fitting designed to connect two metric tubes of different diameters while facilitating a secure transition through a panel, tank wall, or enclosure. This fitting features an elongated threaded body and a heavy-duty locknut, allowing it to be rigidly mounted to a bulkhead to protect the tubing from mechanical stress and vibration at the point of penetration. By incorporating a high-precision double-ferrule compression system on both ends, it ensures a leak-proof, torque-free seal that maintains high-pressure integrity. It is an essential component in sophisticated industrial layouts, such as water treatment systems and fluid control panels, where it provides a streamlined and professional method for reducing line sizes across system boundaries.
