A Union Cross is a four-way tube fitting designed to connect four equal-size tubes at a single junction, allowing fluid or gas flow in four directions. Featuring precision double-ferrule compression ends on all four ports, it provides a secure, leak-proof, and vibration-resistant connection without the need for welding or threading. Its compact cross-shaped design makes it ideal for branching or combining tubing lines while maintaining system integrity.

Manufactured from premium-grade Stainless Steel 316, Stainless Steel 304, Brass, Monel, Hastelloy, Inconel, and other special alloys, the Union Cross is engineered to withstand high pressures, elevated temperatures, and corrosive environments. The precision-machined body and ferrule system ensure reliable sealing, easy installation, and repeated assembly without compromising performance.

Union Cross fittings are extensively used in instrumentation, hydraulic, pneumatic, chemical processing, oil & gas, petrochemical, power generation, semiconductor, pharmaceutical, and process control industries, where dependable four-way tube connections are required. Their robust construction minimizes maintenance while ensuring long service life under demanding operating conditions.
