Union Cross fittings are made from high-grade materials such as stainless steel, brass, and carbon steel, providing excellent durability and corrosion resistance. Stainless steel variants are widely used in chemical and marine environments, while brass options are ideal for plumbing and instrumentation due to their lightweight and rust-free nature. Carbon steel versions are preferred for heavy-duty industrial applications where high strength is essential
Union Cross fittings are designed to connect four tubes or pipes securely at a single junction. They ensure a leak-proof and stable connection that allows fluid or gas to flow in multiple directions. Precision machining of threads or compression ends guarantees a reliable fit, maintaining system integrity even under high pressure
These fittings are used extensively in industries like oil & gas, petrochemical, water treatment, hydraulic systems, and instrumentation. They are ideal for complex piping layouts where multiple branch connections are required, ensuring smooth fluid distribution and operational efficiency.
Union Cross fittings feature a compact design that allows for quick installation without specialized tools or welding. They can be easily removed for maintenance, repair, or replacement, reducing downtime in industrial operations. Their threaded or compression design also simplifies assembly in confined spaces.
Manufactured in line with ASTM, ASME, SAE, and ISO standards, Union Cross fittings ensure top-quality performance and compatibility with other components. Each fitting undergoes rigorous quality checks and pressure testing to guarantee safety and reliability in demanding conditions.
