CROSS UNION
CROSS UNION
The Cross Union is a four-port tube fitting designed to connect four tubes in a cross-shaped configuration. It provides a simple and reliable way to branch off multiple lines at a single point, allowing for efficient fluid or gas distribution in complex systems. Each port is equipped with METALOK INDUSTRIES® – compatible compression fittings, ensuring secure, leak-tight connections. The Cross Union is ideal for use in applications such as instrumentation, hydraulic circuits, and process control systems where multiple connections are needed in a compact space. Available in sizes ranging from 1/8” to 2” and 3mm to 50mm, it is made from high-quality, corrosion-resistant materials like Stainless Steel (SS), Brass, Duplex, Monel, and Hastelloy.
